UNIX C HTTP request returning 301 Moved Permanently - c

Question

I am familiar with the 301 error code but new to http requests and formatting them correctly.
In my program i need to retrieve my school's homepage, but i get a 301 Moved Permanently header. The header's location says where the page moved to, but even that new location won't work for me, probably because i didn't format it correctly.
Initially i send this request:
GET / HTTP/1.1\r\nHost: www.cs.uregina.ca\r\nConnection: close\r\n\r\n
And receive this header:
Received: HTTP/1.1 301 Moved Permanently
Date: Tue, 04 Nov 2014 05:38:42 GMT
Server: Apache
Location: http://www.cs.uregina.ca/
Connection: close
Transfer-Encoding: chunked
Content-Type: text/html; charset=utf-8
What should my new HTTP request look like to get the above moved webpage?
If i try the location of the moved page like it suggests then i get the following 400 Bad Request Response:
GET / HTTP/1.1\r\nHost: http://www.cs.uregina.ca\r\nConnection: close\r\n\r\n
Received: HTTP/1.1 400 Bad Request
Date: Tue, 04 Nov 2014 05:52:36 GMT
Server: Apache
Content-Length: 334
Connection: close
Content-Type: text/html; charset=iso-8859-1

This is exactly what I get when I request cs.uregina.ca. You have probably connected to cs.uregina.ca (or some subdomain other than www), or to an IP address the does not correspond to www.cs.uregina.ca.
If i try the location of the moved page like it suggests then i get
the following 400 Bad Request Response:
GET / HTTP/1.1\r\nHost: http://www.cs.uregina.ca\r\nConnection: close\r\n\r\n
Received: HTTP/1.1 400 Bad Request

This is not surprising. You must remove the http:// protocol from the Host: header. Eg:
GET / HTTP/1.1\r\nHost: www.cs.uregina.ca\r\nConnection: close\r\n\r\n
In general, when requesting a URL such as the following:
http://domain.example:80/path/to/resource/?query#fragment
---- -------------- ==------------------------
protocol host | path
port
you would:
resolve the host name to an IP address, and connect to that IP address on port (if present in the URL) or the default port associated with the protocol.
Communicate with the server using a mechanism specific to protocol. In this case, an HTTP request.
Request path from the server with an appropriate Host: header (in case there are multiple hosts on the same IP).
The fragment identifier is used with (X)HTML and is not actually sent to the server.
The request should (at a minimum) look like this:
GET /path/to/resource/?query HTTP/1.1
Host: domain.example
Connection: close

If you just want the homepage, download nc and type "nc www.cs.uregina.ca 80"
When nc starts type the following and then hit return twice:
GET http://www.cs.uregina.ca HTTP/1.0
