I found a two small problems in
CDdb::SendRemoteMessage, for which I'm submitting this
1. The "User-Agent" header was misspelt "UserAgent"
(needs an hyphen according to RFC2616). I also changed
the RFC822 reference to the correct RFC2616.
2. There was no "Host" header being sent. This one is
required when accessing a virtual host (a domain at an
IP that handles several domains).
I'm attaching a diff of these changes.
