    I'm allowing users to upload a file, using radUpload in one of my applications.  In production, when I upload a file more than 30mb, I get the following error immediately:

    403: Access Forbidden

    Due to the presence of characters known to be used in Cross Site Scripting attacks, access is forbidden. This web site does not allow Urls which might include embedded HTML tags.

    I have verified that it's not the file name.  I have created two files called "myUpload20.zip" (20mb) and "myUpload40.zip" (40mb).  The 20 mb uploads fine.  I can't replicate it in Dev and UAT environment.  In these environment, I am able to upload files over 40mb with no issues.  I have verified the web.configs in all 3 and they all have:

    <!--file upload size 100mb : 30 min-->

     

    <

    httpRuntime maxRequestLength="102400" executionTimeout="1800" />

    Is this a server issue? Any ideas how I can eliminate the error?

    Hello Scott Rupp,

    To localize the problem - please replace RadUpload with the standard FileUpload control and let us know if you get the same error.

    Thanks for the tip. I used the asp.net fileUpload control and the same thing happened.  I don't manage the webserver, can you provide me some input on what to ask/tell the people who manages the server?  I brought this up before to them but got nowhere.

     

    Your help is appreciated.

    Hi Scott Rupp,

    I suppose this is a firewall issue and you can ask about that the hosting company.
