Subject Connection not timing out
Date Wed, 26 Nov 2003 15:33:17 GMT
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
