maxRequestLength+maxAllowedContentLength+HTTPS not working

I have made a service that i host on an azure webapp. This will be used to upload files. IIS has a built in security feature that limits the file upload size.

To work around this i have put the following in my web.config

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="80000000" />
      </requestFiltering>
    </security>
</system.webServer>
...
    <system.web>
       <httpRuntime maxRequestLength="80000" targetFramework="4.5.2" executionTimeout="9000" />
    </system.web>

This is however not working for me. As soon as i upload a large file (50mb for example) it hits me with a 404. When i upload a smaller file (10mb) it works fine. The service is a soap and is called over https. The call does not time out, the exception occurs within 5 seks of the call being made, my guess is it uploads 30mb and then it thinks it is under attack and aborts.

Am i missing something here?

In my case, the problem was because the configuration of httpProtocol in the web.config file had the 'allowKeepAlive' in false.

 <httpProtocol allowKeepAlive="false">

I deleted the allowKeepAlive="false" (making it uses the default value of true) and all worked with big files (configuring the 'maxrequestlength' and 'maxallowedcontentlength')

For classic ASP users also check this settings in addition to the web.config settigns:

IIS > CLick on Website > ASP > Limit Properties > Maximum request entity body limit

I did that configuration, but i fixed my problem putting on my ControllerBase something like:

        protected override void OnResultExecuting(ResultExecutingContext filterContext)
    {

        base.OnResultExecuting(filterContext);

        if(filterContext.Result.GetType().Name == "JsonResult")
            filterContext.Result.GetType().GetProperty("MaxJsonLength").SetValue(filterContext.Result, int.MaxValue);
    }

You can go to folder:

%windir%\system32\inetsrv\

run command:

appcmd set config -section:requestFiltering -requestLimits.maxAllowedContentLength:80000000

or if you only want to set it for your app, run this:

appcmd set config "Default Web Site/" -section:requestFiltering -requestLimits.maxAllowedContentLength:80000000

also you need to update overrideModeDefault to 'Allow' in web.config:

<section name="requestFiltering" overrideModeDefault="Allow" />

Then you can have your web.config updated with appcmd.exe

Hope this article and this article will help you.

About how to use appcmd.exe, you can see https://technet.microsoft.com/en-us/library/cc772200%28v=ws.10%29.aspx

After that deploy your project to azure webapp and try again.
