Key identifies the object in the cache. Every unique key is one cached object. Think of cache as of jav.util.Map - and key is the same thing as the key of the Map. Validity object is to check whether this cached object is still valid or not. Whether to use cached object or discard it and regenerate content from the scratch. For XSP with DB access, validity could be last modification time of the database record. > Say, if I am generating the same key, does that mean the object is cached?

Yes. > I want to cache based on the input url/request-parameters in some ways... > does that simply mean I have to write my own CacheValidity class? Most of the cache validity classes already written. However, in your case, consider adding request parameters to the key. Cacheable.xsp already have something similar - caching depending on request parameter.
