IIS7 File Upload Limit

I encountered this while uploading a large file to an ASP.NET handler, seems like there’s a default limit of ~30MB for a single request in IIS7 on Windows 7.

After some researching, I found that there’s a setting inside <system.webServer> other than the regular limit in <httpRuntime maxRequestLength=".."/> (god and MS know why the duplication).

To fix that do one of the following:

Option 1: Add to your Web.config the following code, under the appropriate nodes:

<system.webServer>

<security>

<requestFiltering>

<requestLimits maxAllowedContentLength="2147483648" />

</requestFiltering>

</security>

</system.webServer>
