You could have the hrefs to these external links point back to the search
servlet with a parameter set indicating the redirect address
(i.e.href="myservlet?redirect=http://othersite.com/wherever.htm";), and
handle these requests by removing the vector, then issuing a redirect.

> Hi, there are certain queries a user may make that return many results

>
> My way to handle this was to put all results( large vector) in session,
> then allow the user to scroll thru results(next, previous buttons). So
> this means there is only one query rather than many.
>
> Now people r worried when to know to take it out of session to free
> memory, in an elegant way design wise. In other words if the user clicked
> on anything else on that page(links to other servlets) other than the next
> , previous buttons, we can assume there is no longer a need to have that
> large vector in session. But what is the elegant way to remove the vector
> in the other servlets? Just simply check for this object and remove it?
> Has anyone else had to design something like this? Thanks.
