Session Failures

That version isn't online anymore. It was a quick hack, and I wasn't happy with it. I haven't had time to publish an updated version.

And I'm not sure that solves your problem. I think we first have to understand what happens, before we start fixing it. If you don't use ajax, and your rewrite rules are ok, and you only have sequential requests from any given user, than you shouldn't have an issue with sessions and id rotation.

Time for some debugging. Set the 'sess_time_to_update' to something small, like 15 seconds. Enable the profiler, so you can see the contents of the session after each page request. Disable session cookie encryption. Use firebug to see what cookie information is send to the browser, and try to determine what has happened when you seem to loose your session? Is there an ID mismatch? Did the ID rotate? When did this happen?

With regards to rewrites: some (most?) people use very simple rewrite rules, advocated by a lot of people here, that basically say "if it's not an existing directory or file that is requested, rewrite to index.php". Which means that requests for missing images (missing, misspelled, etc) causes a second CI request). It is better to have your assets in an /asset directory, and exclude that directory from rewriting using RewriteCond.
