Examples of HTTP 1.1 Requests and Responses

This section provides some tutorial examples of HTTP 1.1 requests and responses. Real examples from perl.org and w3.org Web sites are included.

Let's use my Perl socket test program to send HTTP 1.1 requests to some popular Web servers.

HTTP 1.1 request requires the "Host" header line. I need to create a new request file with an extra line, http_1_1_get_perl.req. Don't forget to have 2 new line (\n) characters to end the file.

GET / HTTP/1.1
Host: www.perl.org


Here is my test with www.perl.org. It used to be working in 2009. But now it is not responding. I have to break the call with <Ctrl-C>:

C:\herong>perl SocketRequestResponse.pl www.perl.org 80 \ 
   http_1_1_get_perl.req http_get.res

<Ctrl-C>

My second test is www.w3.org. I used to be working in 2009. But now it is returning the 400 error:

C:\herong>more http_1_1_get_w3.req
GET / HTTP/1.1
Host: www.w3.org

C:\herong>SocketRequestResponse.pl www.w3.org 80 \
   http_1_1_get_w3.req http_get.res

C:\herong>more http_get.res
HTTP/1.1 400 Bad Request

Looks like my request is missing some required headers.
