>Description:
I want to be able to cache dynamically generated content using mod_proxy.
My code sends an Expires: header, but because it's dynamically generated, there
is no Last-Modified header. Consequently, mod_proxy does not cache the asset.
>How-To-Repeat:
Write a CGI that sends an Expires: header. mod_proxy won't cache it.
