Hi,

What is servlet Filter? What is the use of it? Any on-line tutorial for beginners will be helpful.

Filter is just a complement to the servlet technology.

Filters are used for
- Request Authentication
- Data encryption
- Data compression
- Logging
- Image conversion, etc. .

Hi,
Thanks for your reply. I want to know how to use it. That's why I asked some on-line tutorial to start up. The book in which I am learning servlet doesn't cover the filter, servlet-applet communication, inter-servlet communication. I am try to know the concepts and how to implement it one by one.
