Re: HTImProxy configuration variable

> What is the meaning of the HTImProxy configuration variable in HTAccess?

The meaning of this is to be able to distinguish between a client application
and a proxy server. When Ari made the proxy server, the library was in a bad
state and he moved a lot of the functionality to the daemon. However, I am now
implementing a lot of this in the library, so the variable will be less and less
important.

Unfortunately there is a bug in the code which makes that HEAD doesn't work
(funny, I would swear that it worked 10 minutes ago ;-) ). You can fix it
by applying the patch below.
