>
>
> hi,
>
> I have a jsp search page searchForm.jsp, the commit button will invoke a
> servlet which going to implement the bussiness logic and store the result
> object in a session object named "geCollection", then this servlet will
> redirect to the result.jsp page and display the results based on the value
> stroed in the session variable "geCollection".
>
> the result.jsp display for the first search is fine.
> the result.jsp has a begin a new search link, if I do a new search, the
> result.jsp for the new search is also fine.
>
> the PROBLEM is after I saw the result from new search, if I go
> back with the
> browser back button to find the previous search result, I noticed that the
> previous results page showing the same as the new search results.
>
> I realized that the reason is everytime the servlet is invoked,
> it going to
> store the new results in the session object geCollection . on the
> result.jsp page, it will retrive out data from geCollection. so
> the new data
> will overwrite the old one.
