As memcached (or the module implementation?) does not like some 
characters in the key some request_uri fails.
I am implementing a "live search" that uses AJAX and first hits nginx 
and sees if the requested data is memcached and then failbacks to apache 
and PHP that then sets the the data in memcache.
