[squid-users] reverse proxy headache

Hi there,

I've succesfully configured squid as reverse proxy, and it's been
running fine for 2 months now.
I even got it to sort diferent urls to different servers according to
dstdomain and url-regexp rules.
Now, I just added a new domain to proxy and the answer I get is this:

ERROR
The requested URL could not be retrieved

While trying to retrieve the URL: http://www.laaficion.com/

The following error was encountered:

    * Unable to forward this request at this time.

This request could not be forwarded to the origin server or to any
parent caches. The most likely cause for this error is that:

    * The cache administrator does not allow this cache to make direct
connections to origin servers, and
    * All configured parent caches are currently unreachable.

The configuration is a bit odd, since I'm running some apache and IIS
servers on different machines on port 80, and also an apache server on
the same machine on port 81. The problem I'm getting is with one of
these domains in port 81, however I had succesfully proxied a
different domain on port 81 before (ACL RIOS)

My squid.conf is this:

The new domain and corresponding ACL is: .laaficion.com and ACL AFICION

I'd appreciate any pointers to what's wrong with this config.

Thanks in advance,
