I currently have IIS 6 running on a windows 2003 server, we are using iis with the asapi redirector which passes off to Tomcat. The problem we are running into is that I am getting a Request Entity Too large 413 error. We are not using SSL, but we do transmit headers from our single sign on solution. When a user access this site if they are authenticated it redirects them to our login page. This page is protected via a SSL cert. We pass information such as name, memberof etc in our headers so programs can determine security and display profile information. I have tried increasing the uploadReadAheadSize to insane amounts like 1-5MB and it still doesn't work. Does anyone have any ideas on how I can get this to work?
Depending upon what version of the IIS Tomcat Connector and Tomcat you are using, you may be able to set the max_packet_size to a value higher than the default to resolve this. The Workers Reference has details on the max value for this parameter and the change you need to make on your Tomcat instance.
