Caching intro

Well .. before i started going through the websphere commerce caching features. I was under assumption only JSPs, Static content only can be cached for easy access.

IBM Websphere commerce cache almost everything like JSP, Sevlets, Commerce commands.
What are other features IBM WC provides for caching?

• IBM WC verifies if content of cache is valid . And this validation is run on rule based, time based , group based(What is this? got to find out)  and programmatic.
• If you have multiple servers it can replicate caching on all the servers.
• When you are restarting server large chunk of cache will be preserved to reused after restart. ( this is really news to me. Most of the time we restart server to ensure there is no cache is present on server. IBM WC does a smart saving of cache) So next time if you are still seeing old data after restart remember to clear cache using cache monitor.

Now question is how are we going to enable above features and where. Here is the answer cachespec.xml

Based on type of content some content of data can be cached at browser level , If data is more secured then cache data at server level ( more secure) . IBM WC can cache full page or partial page based on what you define.

I will cover Cachespec.xml and how to utilize better caching.
