load sharing and webtest.fedora

[Elliot Lee]

Ahh yes...

So one option is to make webtest be a passthrough to the app servers,  
and then have all the actual content creation and storage happen on  
the app servers. That'd still require synchronizing content across  
multiple servers, but it'd be more manageable and elegant perhaps.  
Right now we have a decent setup for handling database-driven  
content, but not a great way of managing the tons of static content  
that is out there waiting to be made available.

Us infrastructure types can get together at our regular IRC meeting  
time and chat about this and other items.

Best,
