I am going nuts trying to figure out why:
An application created using Jdeveloper 3.2.3. Some pages send XML as response. When using Jdev, JSP/Web-to-go server everything is fine. Now trying to migrate to TomCat 5.5. For pages that return XML, I am noticing a rather 'hang' like behaviour as if client is waiting for something:

I put a time stamp at beginning and end of my processing. Elapsed time is 20ms. Page size < 500 b. All done locally. Browser (Internet Explorer) takes about 9s to display the XML. Page is buffered (32K, though doesn't help, autoflush on). I even tried with SetHeader(Connection, close) no luck.

Similarly my client makes a bunch of call to such JSP pages returning XML. Each time the processing supposed to happen is of the order of 20-100ms. But the client seems to be 'waiting' gaps between timestamp for next request spans more than 10s (and higher). The client uses Microsoft's IXMLHttpRequest (MSXML v3). Any ideas what could be happening?

Also any reason for cookies not be written by Tomcat (the Jdev does write that)

mucho gracias
