title: Session Problem with multiple Tabs
body: <p>I have a search on my page where you have a filter Menu, a option for sorting, and a Pagebrowser. The Customer wanted, that if he searches something and clicks on a product and then clicks "back" or on "search" again, that the same search and results are shown again.</p>
  
  <p>I dont want to pass all the Search Params with each link (bad urls), so I store all this data in the session. This works fine but there is one Problem:</p>
  
  <p>A users opens the search and filters by "size=big" then opens a new tab and changes the filter to "size=small". There is now "size=small" in his session. So if he switches back on his first tab and clicks "page 2" there, then he sees the second page, but not for "size=big" as he expected, but for "size=small".</p>
  
  <p>Is there a nice way to fix this without passing all the variables (many!) around all the time?</p>
