Session Time Out For UNLOGGED USER During Search -pls help

Question

Hi,
The problem lies in searchresultscontroller.java/searchcontroller.java file under search/web/handler of an application that supports educational note sharing.
The problem is that -
When I search with query strings in different fields(as you will find in the above mentioned java files)..the keywords in resourcedto and get some files as search results.
Then I click on one of the file from within the search result and visit the file.
Here if I m logged in as an user, and the session time out is set to 1 minute in the web.xml file of the web folder not the admin folder then when I hit the BACK TO SEARCH button it easily goes back to the previous search result page along with the queries string that I had input previously.
The problem is that when I m NOT LOGGED in as an user, and I've performed a search with queries and other dropdowns in the search panel, I get the search result page, I visit the file by clicking on one of them but when I hit the BACK TO SEARCH button I don't see the previous search result page from where I had navigated to view the file.
Please suggest on what changes shall I make in the code so that even if I m not logged in as an user, I get back to the search result page on hitting the BACK TO SEARCH button from the file view page.Sir I m herein pasting the code of the searchresultscontroller.java file, but please feel free to ask for anyother file whose code you might want to see.
