 |
|
| So I'm just wondering, if I get a website's IP address how come most of the time I can't just connect to it? For example, if I try to visit my site through the IP it always gives me a "can't connect" error. ?

| Since different websites may be hosted at a single IP address the host will check the domain name that is sent in the HTTP header to determine which website is being viewed. So that might explain why it will deny "direct connections" to that IP.

| Yeah, as tombana, the requested website might be written in the HTTP headers. You need to send eg. (which is mandatory IIRC) to get the specific website, if there are multiple sites hosted on the same IP.

@Jani Usually if there are many hosts on one shared IP address, it is still possible to connect by IP.
For instance, we have IP: 100.600.10.30
Our site name: www.example.com
We connect to www.example.com by doing: 100.600.10.30/~example/. All we do is take the first 7 characters from the site name and add just like the example to get a connection to the site if the IP is shared.

Jani is correct: the 'Host' field in the http headers is mandatory since HTTP/1.1
So the server shouldn't have to show any webpage when the host is not specified. Many servers however will also work without specifying a host field.
