tough servlet mapping problem

Hi. Here is the problem. I have a dispatcher servlet, who handles request for some sites. The servlet is the same, but it dispatches requests for two kind of sites : - some that have their own domain name (www.realname.com) (1) - some that lie under a generic domain (www.domain.com/realname) (2)

My approch is: - open a URLConnection to a servlet (send sessionId, data, ...) - the servlet sets the data in the sessionBean - use RequestDispatcher to forward to the jsp side. __ Der Austausch von Nachrichten mit Software

Re: Session is really not a simple stuff...

Thank you very much Hans, and also Sushma. Your explanations have made my ideas really clearer on the subject. It is always a pleasure to see that many people can take time to share their knowledge and abilities with other programmers. It is a very nice attitude and I admire that behaviour.

Re: sendRedirect problem

Send redirect is done via sending an error code and an error message, you can't send an error code AND an HTML response. You have two options, forget the ok message. Or build a complete response that uses either a javascript of a meta tag to perform the redirection -Original Message-
