Web Application is unloaded from the server question

[John Cruz <jo...@dialogic.com>]

First of all, I'm new to Tomcat so forgive me if this question was
already posted. I did not find the answer in the archives.

I'm using Tomcat 5.5.20 (Standalone) JVM 1.5 from Sun, on a Red Hat
Linux Box OS version 2.6 on i386 box.

I was under the assumption that when a session timeouts, the specific
Web Application is unloaded from the server; thus, reducing the runtime
memory footprint of the tomcat server. 

Is this correct and if so why don't I see this result?...I have set the
my Web App session timeout to 2 minutes in order to accelerate the
behavior.

I'm most concern in keeping the tomcat runtime memory to a minimum then
how fast a page is loaded.

Not true.  When a session times out, only that particular session object
and anything it is the sole referrer of is a candidate for garbage
collection.  Webapps are not removed unless they are undeployed.

Memory is cheap, annoyed users aren't; you might want to rethink your
priorities.  Of course, you should insure your webapps aren't resource
hogs, be that memory or any other finite entity.
