Commented Unassigned: Maximum request length exceeded [1696]

Hi,

I have a virtual application (Composite C1) in IIS 8.

The site has a file picker to upload files to the server (in our case the the files are uploaded to NAS drive). If the file to upload is heavy, I receive the following message:

---

Server Error in '/' Application.

--------------------------------------------------------------------------------

Maximum request length exceeded.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Maximum request length exceeded.

Source Error:

To solve this I have read a lot of posts, and I have made the following changes in the web.config of my site:

Add this entry in <system.web>
<httpRuntime maxRequestLength="524288" executionTimeout="120000" />


And another one in <system.webserver>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="524288000" />
</requestFiltering>
</security>

Other tasks, in this case using appcmd.exe

C:\Windows\System32\inetsrv>appcmd set config "Site" -section:requestF iltering -requestLimits.maxAllowedContentLength:524288000

Even with this tasks done, I am still receiving the above error message.

In the EventViewer the ID is: 1309, Event code: 3004, Event message: Post size exceeded allowed limits.



Some idea? Thanks!

If you are running a 4.0 beta, upgrade to the release and you should have limit of 512 MB for uploads.

To just get the web.config settings you need check ~/Composite/web.config in the 4.0 release - there are two changes near the top which expand the upload limit to 512 MB.
