Sorry for the somewhat flakey operation of the web server today.

     I tried to implement two different server optimizations, Apache’s caching in concert with memcached.  This mostly worked but occasionally corrupted pages so I had to back it out.

     Then I tried to run mod_pagespeed, a Google Apache optimization module, but it did not peacefully co-exist with provisions we use to run dynamic code under the user id of the user that owns that code resulting in all sorts of random permission errors.  So ultimately I had to back that one out as well.
