Default Limits <limits> for IIS Express

Question

I need to test a file upload component that will be accepting very large files. I want to test locally in my development environment but since I use IIS Express instead of IIS 7 I am not sure where to make the global change.

In IIS 7 the change cannot be made via the web.config but needs to be changed through the IIS Manager Tool. See this IIS article for an example.

Does anyone know how to make the same global change using IIS Express (in Visual Studio 2013)?

Answer 1

If the web.config change ppascualv suggested doesn't work, try putting it in the IIS Express applicationhost.config, which can be found at

%userprofile%\my documents\iisexpress\config\applicationhost.config

under

<system.webServer>

put

<security>
    <requestFiltering>
        <requestLimits maxAllowedContentLength="524288000"/>
    </requestFiltering>
</security>

This should set it as a global, unless a web.config from an application overrides it.

Answer 2

You basically need to set both in web.config maxRequestLength and maxAllowedContentLength to upload files.

• maxRequestLength Indicates the maximum file upload size supported by ASP.NET
• maxAllowedContentLength This specifies the maximum length of content in a request supported by IIS.

Note:maxRequestLength is in kilobytes & maxAllowedContentLength is in Bytes

By default, Machine.config is configured to accept HTTP Requests upto 4096 KB (4 MB) and it is reflected in all your ASP.NET applications. You can change the Machine.config file directly, or you can change only the Web.config file of the application(s) you want to

<system.webServer>
        <security>
            <requestFiltering>
                <requestLimits maxAllowedContentLength="524288000"/>
            </requestFiltering>
        </security>
</system.webServer>

 <system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
   </security>
 </system.webServer>
