One common cause of connection resets is HTTP headers that are too large for the base-line ACE configuration.  This can happen if there are a lot of cookies sent by the server web application (use a tool like HTTP Fox to see the headers). 


If the maximum (4K I believe?) is exceeded, the ACE simply sends a TCP RST.


You can up the maximum HTTP Header size with an HTTP parameter map.
