If Tomcat is creating the threads, then they are being used to handle the requests from a server perspective, not a client perspective. So, if your Velocity template "includes" 3 resources and uses 3 separate threads to fetch that data using a loopback request to Tomcat, then the threads are either being launched by your code of Velocity, not Tomcat. > Finally, I noticed that this problem does not happen if I set the > Windows registry key HKCU\Software\Microsoft\Internet Explorer\Main > – TabProcGrowth to 0 or 1, which forces Internet Explorer to use > one process for all tabs, not one process for single tab (which is > the default). When your template evaluates, does it open extra tabs or something? It would seem that the above setting in the Windows registry shouldn't change anything that happens on the server if only a single request is being handled. > Do I miss some configuration settings?

It's hard to understand what's going on, here. Can you give a lot more detail? Take us step-by-step through the process, and be as specific as possible. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJULGcOAAoJEBzwKT+lPKRYNrwP/3H95QkHRDCbCvo0P92P9wav fZ+EsQQToN3EJv2aX2KCpmuj3orkwLols5rg1dEEt2aqlcLr4kc7i+fR2V5euW1o HXqr9dtQbzUQcqMD+8wfW0oGyXmr4F+t1ywaODF2zi9T3tG+JDQ6c9TYE1qWdkdL /BJWkewOK+19ZueqYndae1Jwpu/nVdPV21MSt5j9LQk1cJwsWEqw48f46HzrNJ/2 6mRLVs0hEqyXg/G+XR8b77/2RdnWW7tV3wRbqLdj3uE4/6QNFQBQbhtprAo6LtOD IZhKtNSyRMpZadvxHBSdUzEXrPZPNJ+jOma4M9mZyy4GEH90lkoM+qo8JLC3gO1H kfauuiPK5H++9j5/pda/ZbgdU4qbB2cKLf28uzqQjLIIpLMbm1XBuYo1fUX3vizq pCkgfL4Q8hMfoqQKe89AfcURsLU52LuGEknU5vb/1ZyqamHlFG1Iu3pUlylrcTrN vx/suvTzAjYbzOfaUBHpywW1LAGyvEVj//uyR6aUmCkzOLyNvoAFQCx1cUZkZ31/ Ajm4IL2VOWgacFfrTPy22X4hWF+/v9u0l4uJRVuWJnARjs3pNh17hmttpFyWTVI7 GxY0yI8Xligyr4A0B6mETWewKzwJwznJA1WUCK0e5HUTAdUMtaD8V7AXy2mackr/ N+S8vNrZQf6MQMHdRD9D =m1Pi -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
