After doing a search and selecting a page from the results list, using the back button to return the results page is unsuccesful. A "Webpage has expired" message is displayed in the browser window.

We are currently running 2.4.4#707 but I have seen this behavior in our previous versions as well.

I didn't see any new log entries as a result of clicking the back button but I included all of our logs anyway.
