In order to troubleshoot, we will need your entire ACL / http_access
portions copy/pasted, with sensitive portions edited, if need be.

Here is our environment:

LAN users all go through the proxy for internet access, works fine. A
few users need access to RDP to an external partners Terminal Server.
The terminal server has a Certificate issued by GoDaddy.com. When the
users on the LAN attempt to connect to the external Terminal Server I
don't think that they can authenticate the certificate. I watch the
access.log and I see these lines written:

1297896161.739 70 192.168.x.xTCP_DENIED/407 1962 GET

I have tried putting in some acl's for this but it doesn't seem to make
a difference, here are the acl's as I have them setup:

acl GoDaddy dstdomain .godaddy.com

http_access allow GoDaddy

There are a lot of other acl's that we have setup but did not include
them all, but could if needed. Any ideas about how to get this working?
As a work around I have put in a separate ACL to allow that LAN
computers IP address direct access and it works, but this is not ideal.
