Hola ranchers. I have a few questions. 1. If my context was (mycontext) and I have a servlet which it's url-pattern is shopping/addToCart how to point to this servlet from a JSP page? should I write: <a href="shopping/addToCart">Add To My Cart</a> <a href="/mycontext/shopping/addToCart">Add To My Cart</a> <a href="http://localhost:8080/shopping/addToCart">Add To My Cart</a> I have tried the first one, but it is destroying my app. what is the approach that used in the real sites? 2. I faced this problem: In my app, the session tracking is ok, I have added some books to my cart, then I click show my cart. it is fine with IE6, but when testing it with opera7, it don't work with a consistent way (I am enabling cookies with opera). the first time a clicked show my cart it work, then I added some new books and when clicked show my cart again, it doesn't show the new added books. If the application work with IE6 , why it don't with Opera7?
