Large file doesn't upload in ASP.NET

Question

I have a asp.net web form app, i'm trying to upload a large file (13 mb) in a web form with a FileUpload control, when i press the submit button the web browser starts to upload the file. But, when the web browser finish the upload the app crash without reason, and doesn't lauch any exception, and not enter to the click event code (c#) of the submit button. In my web.config i have set the maxAllowedContentLength option and the maxRequestLength option.

<system.webServer>
<security>
 <requestFiltering>
    <requestLimits maxAllowedContentLength="52428800" />
  </requestFiltering>
</security>

<httpRuntime targetFramework="4.5" executionTimeout="900" maxRequestLength="2097151" />

This is only happening in the web server(Windows Server 2012), in my local server this is not happening. In the webserver show a default error (I don't manage the server, so i can't see what custom error is happening)

i don't know why this is happening, because in the web server are apps with file upload options even more bigger.

Thanks for your help.

My first would be permissions on the folder you are uploading to. Is this a folder you have uploaded to before? Can you manage permissions on the folder? — Chris Morledge

I can upload smallest files in that folder. In the folder "Everyone" can read and write files. And after to uploading the files, the writefile code doesn't execute. — Andres Felipe Ruiz

Modify your web.config by following Stricture, Here I'm using max File request length 13 MB & max Allowed Content Length 1 GB.
Now change Behind the <system.web> in web.config

<httpRuntime targetFramework="4.5" maxRequestLength="13631488" executionTimeout="9000" useFullyQualifiedRedirectUrl="false" minFreeThreads="8" minLocalRequestFreeThreads="4" appRequestQueueLimit="1000" />

And Behind the <system.webServer> in web config write this Code

<security>
  <requestFiltering>
    <requestLimits maxAllowedContentLength="1073741824" />
  </requestFiltering>
</security>

Thanks

the problem was a restriction on the server by the admin that doesn't allow upload large files. All the configuration given in this thread are correct.

It looks like you're missing the opening "security" tag in your web.config

<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="52428800" />
        </requestFiltering>
    </security>
</system.webServer>

Sorry i write it manually, and i forgot to put it. In my original web.config the opening tag is there.

If your maxAllowedContentLength has a big value, your executionTimeout must be big, too! It work in local because you don't need a long time to copy file in your hard. But when you upload your site in server, you need more executionTimeout.

Add a executionTimeout tag to your web.config with a big value.

Change it to a big number like 90000.

Your maxRequestLength is very big and it need and it need a very big executionTimeout.

Add executionTimeout with a big value too your web.config file.
