We've got a .NET application as a front end with a Java based ECM solution as a backend. So the front-end does requests to the back-end through IIS.
The issue is that it works fine for GET requests, but POST requets are most of the times really slow (not always).
We've tried doing POST requests using the POSTER plugin for firefox and it works fine (it takes less than a second per request) while the .NET app takes sometimes more than 20 seconds. I have to say that we've debugged the .NET app, and it doesn't seem to be anything in it, so my suspects led me to the IIS...
Any ideas?
