I'm trying to upload a large file (40mb) via file manager.  I get the folowing error.

HTTP Error 404.13 - Not Found
The request filtering module is configured to deny a request that exceeds the request content length.

I remember this from an earlier problem where i upped the limit in web.config to handle 20 mb files.  I tried doing the same thing for this and changed the settting to 40 mb, same error.  I found some threads on adding an executionTimeout flag, same error.  I've even gone so far as upping the limit really high, but I still get the same error.  Here's my line from web.config currently.  I've raised/lowerd the timemout setting, but it doesn't seem to help anything. 

<httpRuntime useFullyQualifiedRedirectUrl="true" maxRequestLength="100000" requestLengthDiskThreshold="100000" executionTimeout="100000"/>

Any ideas on what I'm missing?  Is there an additional setting in a menu somewhere?  Maybe in IIS 7 that overrides this value??  I'm 99.9% sure that I only changed those values when I upped the limit from the default (8 mb I think) to 20 mb.

Any ideas on this? Still looking for a solution.

Thank chatters. I tried the maxRequestLength which is what I changed before but had no luck.

 I'll take a look at the requestLimits in the url you provided as well. I'd rather stick with the integrated mode however.

Any suggestions from others?
