In IIS, the maximum request size is 4Mb. If you try to upload a file one byte larger, you will get a 404 error.

You need to modify the request limits to allow for larger file uploads. That means modifying your web.config file in two places:

XML

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="10240" />
    </system.web>
</configuration>

XML

<system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1048576" />
      </requestFiltering>
   </security>
 </system.webServer>

NB: The setting under system.web is in kilobytes, whereas the one under system.webServer is in bytes. So to make them match, the second needs to be equal to 1024 × the first.

With this config in place, you will be able to upload files up to 10Mb. If you need to support larger files, then increase the values - you can set any value up to approximately 2Gb.

Solution 1

The error message you are getting is a 404 error: page not found. That has nothing to do with the code you show, it means that the page the user (or a redirect) is trying to access has an incorrect URL and cannot be located.

I'd start by looking at the URL ...
