RE: HTTP request working via hostname but not via IP address

["Omar A. Herrera" <omar.herrera () oissg org>]

Hi Arjun,

Virtual Website != Virtual IP. The same IP can host several virtual websites
that are accessed through the "Host:" header field. This is what Javier
means (the GET header field in your request isn't enough).

You also need to specify your website's name in the Host header field,
within your HTTP request. Refer to RFC 2616 for more information and
examples. 

Regards,

Omar Herrera
