Hi, 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 populated Console: " Created new session-scoped cache in session 94FFF4FAE818657D63DFD96049A9A99A at key: __oscache_cache"
In oscache.properties file cache.use.host.domain.in.key=true cache.path=c:\\myapp\\cache cache.algorithm=com.opensymphony.oscache.base.algorithm.FIFOCache cache.blocking=false cache.capacity=1000 cache.unlimited.disk=false 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... </cache:cache>
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.
