Maximum request length exceeded

Hi:

I created an asp.net to upload files.
My code is written in visual basic.net

When I try to upload a file bigger than my
maxRequestLength setting I get this exception:

(0x80004005): Maximum request length exceeded.

I can not catch the exception even using try-catch-finally

Is there a way to catch this exception?

Thanks!!

Re: Maximum request length exceeded

HttpException (0x80004005): Maximum request length exceeded.

Re: Maximum request length exceeded

asp.net writes the file into memory as client can save the file to the disk. look for machine.config attributes memoryLimit ,processModel

Re: Maximum request length exceeded

You can set maximum request length in web.config

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="32768" />
    </system.web>
</configuration>

Re: Maximum request length exceeded

I have a similar problem. The file size limit is set high on our site, but I get timeouts if it takes longer than a couple of minutes to upload the file. Do not want to catch the error, but rather make a setting change to avoid it.

Re: Maximum request length exceeded

Increase request timeout to desirable time. Remember there are two timeouts "Request" and "Session". you need to increase "Request" timeout.

You can set maximum request length in web.config
<configuration>
    <system.web>
        <httpRuntime maxRequestLength="32768" />
    </system.web>
</configuration>

How do I write some errror checking code in my code behind to handle this error? Instead of keep increasing this number, I want to put out a friendly message to the user about the max size. How do I do that?

Re: Maximum request length exceeded

you can check the file lenght of the file that the user is trying to post to the server then display your message

try
{
   if(fileToBeUploaded > constantMaximumFileSize)
   {
      //display your pretty message here
      messageLabel.Text = "Hey! You can't upload a file more than " +
                       + constantMaximumFileSize;
   }
   else
   {
      //do your upload code here
   }
}
catch(HttpException httpEx)
{
   //HttpExceptions is an exception that occurrs during the processing of HTTP requests
}

HTH

Re: Maximum request length exceeded

That does not work because the error occurs before that.

Re: Maximum request length exceeded

Try the following link and see if that can resolve the issue.

There are 3 other places you can check and adjust the timeout.

IIS --> Select your Virtual Directory ->Right Click for Properties --> Select Virtual Directory Tab-->Click on Configuration--> Select Options Tab --> Change the default TimeOuts for Session and ASP Script Time out

I think default is 20 and 90 seconds respectively.

In ASP.NET, you can write ScriptTimeOut = xxx seconds as you desire.

Try this: http://www.frozendev.com/temp/fileupload.zip

You can do anything once you get out of the while loop...

Re: Maximum request length exceeded

I'm not the IIS admin so I can't really make any changes on the server. In addition, I do not want to keep increasing the size because there is always a user who will try to upload a bigger size file.

Re: Maximum request length exceeded

mychucky, sample project from my web site doesn't require you to be an admin and modify anything in IIS.

Have you actually tried it..?

Re: Maximum request length exceeded

You do not need to increase the size everytime, if you are using .NET 1.1 then you can put the max size which is 1GB if 2.0 then 2GB, I doubt that any user will try to upload in GB. It will not hurt you to put the max allowable size.

Re: Maximum request length exceeded

OK. I'm going to repeat this one more time...

In .NET 1.1, there's only one (correct way) way to do this.

In .NET 2.0, this limitation issue has been taken care of...

You can see .NET 1.1 example of a workaround here. In this example, there's also a commented code, implementing the wrong way --> http://www.frozendev.com/temp/FileUpload.zip

And you can also see what Microsoft did to fix this issue --> http://support.microsoft.com/kb/910436

Good luck!

I can't get this to work in Cassini (Visual Studio built-in testing server), but I can get it to work on production IIS:

Server.ClearError();
Response.Redirect(string, false);

Re: Maximum request length exceeded

FileUp Standard Edition can accept uploads of up to 4 gigabytes. FileUp Enterprise Edition can accept unlimited size uploads. However, when using the product in .NET, it is important to configure the application settings to make sure ASP.NET doesn't block the large uploads before FileUp can process them.

The maxRequestLength parameter is set in the httpRuntime section of web.config (or machine.config). maxRequestLength is set in kilobytes. So, for example, if you want to allow uploads of 100 MB, you would set maxRequestLength to 102400.

There are some other settings in httpRuntime which you may want to modify for large uploads. Below is an example httpRuntime element. Please adjust the settings according to the needs of your application.

<httpRuntime 
      executionTimeout="1200" 
      maxRequestLength="102400" 
      useFullyQualifiedRedirectUrl="false" 
      minFreeThreads="8" 
      minLocalRequestFreeThreads="4" 
      appRequestQueueLimit="100" />

For more information about various ASP.NET application settings which apply to large uploads, see the FileUpEE or FileUpSE documentation:

Re: Maximum request length exceeded

To catch the exception you will need to create a Global.asax file in your root directory, then add the method void Application_Error(object sender, EventArgs e) . The Global.asax file handles all the Application level events for your website... the Application_Error method will catch all the unhanded exceptions generated by your website.

#1 05-21-2002, 06:37 PM Mark Riordan Posts: n/a Solution to "Maximum request length exceeded." -------------------------------------------------------------------------------- When making a large post, you may see the message: Maximum request length exceeded There are no references to this on MS's website, or anywhere else that I've seen. However, with the help of the Wrox book "Professional ASP.NET", I have found that by default there is a 4MB post limit. This can be changed in machine.config (entire site) or web.config (individual app), by changing maxRequestLength: The above example increases the limit to 51200 KB (50 MB).
