Missing Form Data

BSkelding · April 26th, 2004, 02:25 PM

I've written an app that uploads two files to the web server for further processing. It appears that if the total size is greater than 4 meg it causes an error. Looking at the tracing information it looks like the form data is not being processed. The Session State and Form Collection information is completely missing. Any ideas on what's causing this and how it can be remedied? Is this an issue w/ IIS or the application? Thanks.

Hi Maumee,

It's likely that this is caused my the maxRequestLength setting in the machine.config file for your system. You'll find this attribute on the httpRuntime element, like this:

Code:

<httpRuntime   
  executionTimeout="90" 
  maxRequestLength="4096" 
  useFullyQualifiedRedirectUrl="false" 
  minFreeThreads="8" 
  minLocalRequestFreeThreads="4" 
  appRequestQueueLimit="100" 
  enableVersionHeader="true"
/>

As you can see, maxRequestLength is set to 4096 which equals the 4 MB limit you seem to hit.

To solve this, you can change this in the Machine.config file, or better yet, override the setting in the site specific Web.config file. Look here for more info: http://msdn.microsoft.com/library/de...imesection.asp

Cheers,
