Hi Guys,
I am working on creating some more scalable tomcat applications. I have
addedd a SessionListener and it seems that hitting a jsp page triggers a
session to be created.
If there are 1000 users and only 10 are signed in, I dont think 1000
sessions need to be created yes. How do I turn off
Hi,
Are there any web sites that show/compare the performance of a plain
install vs adding the native libraries for tomcat? How many of you guys
actually use the native libraries in production, ie is this common or
uncommon?

Just wondering if there is anyone who has been or is involved in cross

Are you using mod_jk? There is a config that could cause this.
We did not configure the server, our provider did I just checked

Are you using mod_jk at all? If so, you'll need to look at browser to
