How is this server-side redirection done in PHP? You might do something like: pageA.php ------------------------------------- <? if( user_realy_wants_page_b ) { include( 'pageb.php' ); exit; } ?> Page A starts here... ------------------------------------- That all happens on the server, and does not require anything outside of page A to implement. > 3) In doing the server-side page redirection, variables can be added to a > "request" object, which embodies parameters related to a request.

In the example above, any variables set in page A will be visible in page B when it is included. The values must be set BEFORE the include() is hit. > 5) On a JSP site, I typically arrange things such that a particular JSP (or > servlet) accepts requests, processes them and then forwards them to one of > a number of different pages, depending on the outcome of the processing. > This is in contrast to the alternative approach where one simply goes to a > page, which does some processing and then displays the contents of the > requested page.
