Solution 1:

You can set the maximum allowed content length in the web.config. The default value is 30,000,000 bytes:

<system.webServer>
  <security>
    <requestFiltering>
      <requestLimits maxAllowedContentLength="[maxLengthInBytes]" />
    </requestFiltering>
  </security>
  ...
</system.webServer>
