If I enable memcached on our Joomla based site header redirects end up returning 404 page not found errors. I have 2 examples of issues we're having with memcached enabled...
The first is we do a simple check to see if a user is logged in or not when they go to the root of the domain, if the user is logged in it redirects them from to their profile. This works fine with memcached disabled, but once enabled it gives a 404 page not found error. The second issue is a link we have in a menu to the user's personal library page where they save video, audio, and other resources to breaks. It should read index.php?option=com_library&itemid=1234, however once memcached is enabled in strips out the option=com_library for some reason.
