I'am programming a Portlet to search our website. It is using apache Lucene and is working very good.
Now there is a big problem. Beside the main search window there should be something like a remote control at the top of each page, where you can enter a search term. Then it should open the site containing the search portlet and perform the search.
How can I transmit the needet data from the remote portlet to the search portlet. I've tested using sessions with parameter APPLICATION_SCOPE, but it looks like the session is deleted.
