Hello,

What is the size limit of a file uploaded by a FormFile?

If there is a limit, is it possible to increase it?

Thank you.

Yohann.

Hullo Yohann,

The max size of HTTP-Uploads is restricted by asp.net, not by GMSC. The default request size of asp.net WebApps is 4 MB.

Since uploads from GMSC forms go to the workflow-engine, you should consider to alter the config sections in the web.config file of the Workflow Web Application ({GMSC-install-path}\Program\Workflows\web.config).

For example, to raise the max request size to 10 MB:

<configuration>
   <system.web>
      <httpRuntime maxRequestLength="10240" /> <!-- 10 MB in KB (10*1024) -->
   </system.web>
   <system.webServer>
      <security>
         <requestFiltering>
            <requestLimits maxAllowedContentLength="10485760" /> <!-- 10 MB in BYTES (10*1024*1024)-->
         </requestFiltering>
      </security>
   </system.webServer>
<configuration>

However - be aware that raising the request size limit may open up an attack vector; I would recommend to talk to your web server operators about this.

See https://stackoverflow.com/questions/288612/how-to-increase-the-max-upload-file-size-in-asp-net#18531... for some advice, how the request limit is set in web.config.
