On the server side, asign any new search, either from the same window or a new one, a 'search id', if you will, which you can send back to the server and allows you to identify each search. This search id, a random number, might index an array containing each search request and the whole array stored as in the session data. > I really don't want to > put the search criteria as part of the URI between all these pages and use > GET to pull the data off as the user > could fiddle with the line and again cause problems. At least a session id, being a random number long enough instead of a sequential number, would be cryptic enough that the user would probably not dare touching it and those who do know would know they better don't even try.
