Hi Luccky,

As been rightly said by fellow ranchmate that the concept is well explained in HFSJ. In short what I know about request wrapper and response wrapper object in filter concept is that these are the objects which are wrapped around actual req, resp object then from the filter class these custom objects are sent to the next filter or servlet.

Thanks,
Vikas
