Re: manipulating the http requests.....

how do we call a method of a servlet using RequestDispatcher. With request =
dispatcher we can call a second servlet from one servlet, but if i want to =
call a foo() method inside the second servlet, how do i call it (even after=
 using RequestDispatcher)... thats my question
