Technical FAQs

Question

We are adding files to the viewing session with HttpWebRequests. We noticed with larger files the response is:

(413) Request Entity Too Large. -  at System.Net.HttpWebRequest.GetResponse(). 

What could be the cause?   

Answer

A 413 request entity too large error occurs when a request made from a client is too large to be processed by the web server. If your web server is setting a particular HTTP request size limit, clients may come across a 413 request entity too large response. An example request that may cause this error would be if a client was trying to upload a large file to the server (e.g., a large media file).

Depending on which web server you use, implement the necessary changes described below to configure your web server’s maximum HTTP request size allowance. Below are some suggestions for popular Web Servers:

For Nginx users:

The directive that determines the allowable HTTP request size is client_max_body_size. This directive can be defined in your nginx.conf file located at /etc/nginx/nginx.conf

For Apache users:

The directive is LimitRequestBody which can be defined in your http.conf file or in an .htaccess file.

For IIS users:

  1. Open Internet Information Services (IIS) Manager.
  2. In the Connections pane, go to the connection, site, application, or directory for which you want to modify your request filtering settings.
  3. In the Home pane, double-click Request Filtering.
  4. Click Edit Feature Settings in the Actions pane.

Today’s applications need tremendous versatility when it comes to document management. Developers are expected to deliver tools that can handle multiple file types and have the ability to share them securely with internal users and people outside the organization. As more companies transition to remote-first work environments, online (and secure) collaboration tools are becoming a must-have feature. One of the major challenges facing developers is how to adapt existing document technologies and practices to an increasingly interconnected environment without creating additional risks.

Rendering and Conversion Challenges of Microsoft Office

Microsoft Office (MSO) files have long presented problems for organizations looking for greater flexibility when it comes to viewing and marking up documents. This stems in part from the widespread reliance on the Office software itself, which held a staggering 87.5 percent share of the productivity software market according to a 2019 Gartner estimate. Companies of all sizes across multiple industries rely on programs like Word, Excel, and PowerPoint, but there are many instances where they would like to be able to share those documents without also surrendering control of the source files.

The challenge here is twofold. On the one hand, if an organization shares an MSO file with a client or vendor, there’s no guarantee that the recipient will be able to view it properly. They may not have access to Office, in which case they can’t open the file at all, or they may be using an outdated version of the software. While they may still be able to open and view the file, it may not display as originally intended if it uses features not included in previous editions of Office.

On the other hand, however, sharing files outside a secure application environment always creates additional risk. Microsoft Office documents are notoriously attractive targets for hackers seeking to embed malicious code into files, and older, unpatched versions of the software contain numerous known vulnerabilities. Sharing MSO files with an outside party could quickly result in the file being exposed to a compromised machine or network. There’s also a question of version control and privacy, as a downloaded file could easily be copied, edited, or even distributed without authorization.

Unfortunately, it has proved quite difficult to natively render MSO documents in another application. Anyone who has had the misfortune of trying to view or edit a DOCX file in Google Docs will understand the challenges involved. While it’s certainly possible to render MSO files in a different application, the end result is often a little off the mark. Fonts may be rendered incorrectly, formatting could be slightly (or drastically) off, and entire document elements (such as tables, text fields, or images) could be lost if the application doesn’t know how to render them properly.

Rendering MSO Files Natively with PrizmDoc Viewer

As a fully-featured HTML5 viewing integration, Accusoft’s PrizmDoc Viewer can be deployed as an MSO file viewer that renders them like any other document type. However, this doesn’t provide a true native viewing experience, which many businesses require for various compliance reasons. Fortunately, the PrizmDoc Server’s Content Conversion Service (CCS) allows applications to natively render MSO documents with a simple API call.

The MSO rendering feature allows PrizmDoc to communicate directly with an installed version of Microsoft Office, which ensures that every element of the file is rendered accurately within the HTML5 viewer. For example, a DOCX file opened in Microsoft Word should look identical to the same document rendered within an application by PrizmDoc Viewer. Once the document is accurately rendered, it can be shared with other users inside or outside an organization. This allows people to view and even markup MSO files without the original source file ever having to leave the secure application environment. It’s an ideal solution for reducing security risks and eliminating the possibility of version confusion.

Converting Additional MSO File Elements

In many instances, organizations need to share MSO files that have already been marked up or commented upon. This could include Word documents with multiple tracked changes or PowerPoint slides with extensive speaker notes. Those additional markups could be important elements that need to be shared or reviewed, so it’s critical to include them during the conversion and rendering process.

Using the server’s CCS, PrizmDoc Viewer can convert Word documents with accepted or rejected markup changes when converting the file into a different format (such as converting an MSO file to PDF) or rendering it for viewing in the application itself. The same capabilities extend to PowerPoint presentations with speaker notes. When converting these MSO files, the outputted version can consist of slides only or include the speaker notes along with them.

These conversion and rendering capabilities provide developers tremendous flexibility when they’re integrating viewing features into their applications. They can easily deploy them to help their customers collaborate and share MSO files without having to remove them from a secure environment. It’s also a winning feature for end users, who don’t need to worry about downloading files or having access to the latest version of Microsoft Office.

Improve Your Document Capabilities with PrizmDoc Viewer

With its extensive file conversion, redaction, and annotation capabilities, Accusoft’s PrizmDoc Viewer is an essential integration for any document management platform that requires an MSO file viewer. It provides support for dozens of file types to give applications the flexibility needed to meet the demands of today’s complex workflows and improve efficiency. As an HTML5 viewer, it can be integrated into any web-based solution with minimal development effort, which frees up valuable resources developers need to focus on the innovative features that will help set their applications apart in a competitive market.

Here at Accusoft, we’re always looking for new ways of connecting people with progress to improve productivity and drive innovation. It’s why we put so much work into our standards-based APIs and SDKs. We understand that developers need mature integrations that are ready to enhance their applications from day one and will be supported by extensive, accurate documentation. From the onset of 2020, we had a strategy in place to help us focus on making it easier for our customers to solve their business problems.

And then, well, 2020 happened…

As this challenging year finally comes to a close, we wanted to take a look back at how we adapted to stay focused on our enduring mission to deliver better products and services to our customers.

2020 Customer Advisory Board Meetings

Since most of our products are delivered through APIs and SDKs, we often encounter situations where our customers and partners independently purchase, download, and extend applications with minimal interaction. Historically, this made it difficult to gain insight into how our clients utilized many of our solutions and what features they would like to see from them in the future.

That’s why we hosted our first Board of Connectors (BoC) meeting in 2019 to bring customers and product managers together in an ongoing dialogue about business needs and product strategy. These meetings also had the benefit of allowing our customers to build relationships with our internal teams, provide feedback on product features, share their business challenges, and discuss key development trends impacting their respective industries.

We had the good fortune to hold our first BoC meeting in-person before the COVID-19 pandemic forced us to adopt rigorous social distance and work-from-home protocols for the safety of our employees and customers. Our second meeting took place in virtual format later in the year, which allowed us to learn first-hand how our customers were dealing with pandemic pressures and how we could adjust our product strategies to meet their rapidly shifting needs.

An Eventful 2020 for PrizmDoc Viewer

One of the principal beneficiaries of these meetings was our popular PrizmDoc Viewer solution. As a best-in-class HTML5 viewer, PrizmDoc Viewer was already a powerful and versatile viewing integration capable of enhancing a variety of applications. But if there’s one thing we’ve learned over the years, it’s that there’s always room for improvement.

That’s why we made it a point of emphasis to implement the top five requests we heard at the first BoC meeting of 2020. Despite all the disruption of COVID-19, we’re incredibly pleased that we were able to deliver on every one of these requests. We also rolled out a host of new product features and continued to optimize PrizmDoc Viewer for improved performance.

Here’s a quick rundown of the five big PrizmDoc Viewer upgrades of 2020:

How PrizmDoc’s Video Playback Feature Enhances Legal Applications

Video playback has become an indispensable feature for today’s applications, reflecting the evolution of user preferences and the ubiquity of multimedia content in our digital age. As the consumption of video content surges, from tutorials, entertainment, and online courses to marketing materials and user-generated content, applications that offer smooth and versatile video playback capabilities cater directly to this user demand, enhancing engagement and retention rates.

Moreover, video communicates complex ideas efficiently, appeals to visual learners, and often enhances user experience with a richer, more immersive medium. In today’s highly competitive digital marketplace, integrating robust video playback functionality can be the deciding factor for an application’s success, ensuring that it meets contemporary user expectations and remains relevant in a video-centric digital ecosystem.

Introducing PrizmDoc Video Playback

Given the growing importance of video, the Accusoft engineering team has incorporated video playback into PrizmDoc’s growing feature set. PrizmDoc has long made it easy to integrate seamless document viewing into web-based applications, but the new video playback feature now allows developers to natively embed video functionality into their software. Thanks to PrizmDoc video playback, there’s no longer any need to host videos on external sites or rely upon vulnerable software plugins to incorporate videos into their application workflows.

The new video playback feature carries on PrizmDoc’s longstanding tradition of efficiency and outstanding performance by delivering high quality video content with minimal processing lags and accommodating multiple file formats. As with other PrizmDoc features, developers can quickly incorporate video playback through a simple API call. This makes it easy to roll out video features without having to build complex functionality from scratch.

Video Playback Benefits for Legal Applications

The legal industry stands to benefit immensely from the use of video playback. Incorporating video features into LegalTech applications allows legal teams to work more effectively and deliver better services to their clients. Here are just a few of the benefits of video playback for the legal industry:

Better Case Preparation

Incorporating video playback functionality into legal software revolutionizes the way lawyers work and offers them unprecedented advantages in case preparation and courtroom representation. With video playback, lawyers can revisit crucial deposition testimonies, witness interviews, or surveillance footage at the touch of a button, eliminating the need for extensive manual sifting through transcripts or notes. This visual evidence can be used to enhance comprehension, validate statements, and build more persuasive arguments. 

With the growing use of virtual court proceedings, having integrated video playback capabilities ensures that legal professionals can present key evidence seamlessly, without toggling between multiple platforms. In essence, video playback in legal software streamlines processes, promotes meticulous case analysis, and provides lawyers with a compelling tool to bolster their arguments and client representation.

Improved Communication & Collaboration

Video playback in legal applications offers a transformative advantage by enhancing communication and collaboration among stakeholders. Unlike traditional methods, video captures the nuances of testimonies, allowing viewers to discern tone, emotion, and non-verbal cues often lost in written transcripts. This depth can be particularly evident when observing video depositions, where the demeanor and specific phrasing of witnesses are critical. Additionally, complex scenarios or events can be better understood when demonstrated through video, making it an indispensable tool for lawyers when explaining intricate case details to clients or colleagues.

This sensory-rich medium allows lawyers to brief their teams more effectively, reducing reliance on memory or textual notes, ensuring everyone remains aligned, and facilitating strategic discussions. Clients, too, benefit immensely. Video content can demystify the often-complex legal processes, empowering them with a clearer understanding of proceedings and making them active participants in their cases. Furthermore, when videos are shared with opposing counsel, it can improve transparency and potentially lead to faster resolutions by pinpointing areas of agreement or contention, thereby laying the groundwork for more informed negotiations.

Increased Efficiency

The integration of video playback within legal applications presents a notable advantage in increasing efficiency for legal professionals. In the past, the absence of built-in playback capabilities meant that lawyers often had to download and launch videos in separate external applications, causing interruptions in their workflow. Now, with the advent of direct video playback in the document viewing interface, there’s a seamless transition between reading textual documents and viewing related video content. This streamlined process ensures that lawyers and their teams no longer grapple with the cumbersome process of managing external video files, thereby saving valuable time.

By consolidating tasks within a singular interface, legal professionals can maintain their focus, review case materials more swiftly, and ultimately make more informed decisions without the constant shift between applications. The simplicity and efficiency offered by this integration not only optimize legal workflows but also enhance the user experience, leading to more agile and effective case management.

Enhance LegalTech Applications with PrizmDoc Video Playback

PrizmDoc’s new video playback feature delivers tremendous benefits for legal applications. This enhancement empowers legal professionals to integrate and access video content directly within their LegalTech software, eliminating the need for third-party platforms or external tools. As a result, users experience a swifter and more cohesive workflow, particularly when cross-referencing between legal documents and relevant videos. By consolidating these capabilities and minimizing associated costs, LegalTech software developers can channel their efforts and resources into innovating further, ensuring that their applications remain at the forefront of a rapidly evolving industry landscape.
