[En-Nut-Discussion] How to connecto to a virtual host

[Christoph Eicke]

Hi Jespen,

(actually this message didn't go through and a reply has already been posted, 
but here is my 50cents for this anyways)

in section 5.2 of RFC2616 (http://www.w3.org/Protocols/rfc2616/rfc2616.html) 
is describes what has to be done:

"[...] An origin server that does differentiate resources based on the host 
requested (sometimes referred to as virtual hosts or vanity host names) MUST 
use the following rules for determining the requested resource on an HTTP/1.1 
request:

1. If Request-URI is an absoluteURI, the host is part of the Request-URI. Any 
Host header field value in the request MUST be ignored.

2. If the Request-URI is not an absoluteURI, and the request includes a Host 
header field, the host is determined by the Host header field value.

3. If the host as determined by rule 1 or 2 is not a valid host on the server, 
the response MUST be a 400 (Bad Request) error message.

Recipients of an HTTP/1.0 request that lacks a Host header field MAY attempt 
to use heuristics (e.g., examination of the URI path for something unique to 
a particular host) in order to determine what exact resource is being 
requested. [...]"

This means that the HTTP GET request has to look something like this:

GET /some/file.html HTTP/1.1
Host: www.your.virtual.host.com

I hope this helps.

Christoph
