filtering a request

Hi Everybody,

I need your help for writing a filter for changing the request path for a servlet. Suppose i pass a request

http://localhost:8080/periodicals/electronicsforyou/journal

instead of

http://localhost:8080/periodicals?param1=electronicsforyou¶m2=journal

I want that user type the first url with request path periodicals/electronicsforyou/journal and finally the filter convert that request path into ?param1=electronicsforyou¶m2=journal.

Is it possible. Could you please advise.

Sincerely,
Pawan

It this was an Apache httpd with mod_rewrite it would be so easy...

Can i use Servlet Filters in this case?

Yes you can, and there is a servlet filter clone of Apache mod_rewrite, which may do what you need done: Url Rewrite Filter

But you can also use a simple servlet to do that if you have only this url to rewrite!

In this servlet you just forward to the good url!

you can add simple code in doGet method that tests for these QueryString variables if they are null redirect him to the second path
