Connect to multi-host sites using Winsock

Hi,

I'm newbie to this forum, however, I had worked for years on VB.
I'm designing an Internet Navigator, it is working fine so far, until I got problem with Multi-Host websites.
for example: www.aljazeera.net
when I connect to the site above and request the main page using:

Code:

GET / HTTP1.0

I get:

Code:

HTTP/1.0 400 Bad Request

Can anyone help me on this issue??
