Increasing the Maximum Content Length for File Uploads

Overview

 

Sometimes, you may want to extend the content length for uploading files to your site. 

This article describes the process of increasing the maximum length of the content that can be uploaded on a site. 

 


Process

 

To increase the maximum content length for your site, follow the procedure mentioned below:

  1. Locate the web.config file that is typically present in the root folder of your site.

  2. Add the following parameter to the web.config file. The value in bold is in bytes:

     <system.webServer>
    ...
    <security>
    ...
    <requestFiltering>
    <requestLimits maxAllowedContentLength="104857600"/>
    </requestFiltering>
    </security>
    </system.webServer>
  3. After making the changes in the web.config file, increase the maximum size in DNN. To do so, navigate to Settings > Security.

  4. Navigate to More > More Security Settings, change the value of Max Upload Size (MB), and click Save.



 

Notes: 
  • The value in the web.config file is in bytes, while the value inside the DNN configuration is in Megabytes.
  • It is critical to keep the value in DNN's configuration less than or equal to the value in web.config.
