OSCache tag library

I am using Tomcat 5.5 and using OSCache 2.4.1 to improve the
performance of JSP pages.

When a user logs in, records are loaded from the database, but this
takes too long and the browser freezes until all the records load. To
cache this occassionally changing content from second request onwards,
I surrounded the JSP with <cache:cache> tags.

However, if I refresh the page or navigate to another link and come
back, it still seems to go the database and fetch the records! Can't
figure why it does not cache. The cache is apparently created and
" Created new session-scoped cache in session
94FFF4FAE818657D63DFD96049A9A99A at key: __oscache_cache"

In oscache.properties file
The rest properties are commented out

In the JSP
<%@ taglib uri="http://www.opensymphony.com/oscache" prefix="cache" %>
<cache:cache scope="session">
...jsp content here...

I also enabled disk caching and when I see the cache file, it caches
ok! The content appears in the cache file in c:\\myapp\\cache. Don't
understand why it still goes to the database.

Any ideas?

Where is your code for fetching records from database? Is it the same JSP page where you are populating records and caching?
