Connection not timing out

[Terry Orechia <To...@comcast.net>]

When the client issues a request on Explorer to the tomcat servlet and the request takes longer than the connectionTimeout, the client hangs.   I am no longer able to make any html requests to my  tomcat appliction or the tomcat manager/html application and must restart tomcat.   I am running java web services development pack 1.3 (tomcat version 5) on Linux Red Hat.    If I increase the connectionTimeout value, the problem is less likely to happen, but still occurs when there is a heavy load on the system.      I have put logging statements in my servlet and can see that the servlet request does actually complete after the time limit has expired.  However, the client does not free up.   I can stop the request on Internet Explorer, but any tomcat requests after this initial hang will also hang.    How can I get Internet Explorer to issue a timeout?  Also, how does the disableUploadTimeout parameter work in relation to connectionTimeout?
My server.xml is listed below.
Thanks,
Terry
