I had not considered this important until I saw that
it was happening in my logs.

In the current squid-2.2.STABLE4-1 rpm if someone makes
a request through the squid that uses one of the webdav
extensions like PROPFIND the squid doesn't recognize the
method and will not proxy. The patch in the mentioned
URL fixes this.

I've modified the spec file like so:
