Remebering previous site states

[ahaupt]

Hi all,

I have a site with a search page, which uses session variables to store
the search criteria.

The problem is that the session obviously gets overwritten each time a
new search is done. Thus, if you were to go back or forward with the
browser it'll appear like all your searches have been the same one.

How does the search engines do it. Does it cache the searches somehow
and remove them later on?

Best,
Andre

You can cache multiple searches in Session, but you will have to use a
Hashtable or some other collection to gather them. You can also cache the
results of the query, but realize you might end up overdoing the caching if
you store a lot of information. This is not wise.
