[users@httpd] problems with request line for the apache server
I am currently running Linux 7.2 with Apache version 2.0.49. I am currently having intermittent problems with the "GET" method while running the Apache server. I have read the RFC 2616 Section 5 and it states to put the request in the form of the following:
Request-Line = Method SP Request-URI SP HTTP-Version CRLF
For example, if I perform the following to MSN's website, I obtain the following:
telnet msn.com 80
Trying 207.68.172.234...
Connected to msn.com
Escape Character is '^]'
GET / HTTP/1.0
The results come out as follows:
HTTP/1.1 200 OK (which is the desired result)
.
.
.
(followed by the correct HTML for the MSN home page)
.
.
Connection Closed by Foreign Host.
However, if I telnet to the MSN site and perform the following:
GET / HTTP/1.1
The results come out as follows:
HTTP/1.1 400 Bad Request (which is not the desired result)
.
.
.
(followed by the incorrect HTML for the MSN home page)
.
Connection Closed by Foreign Host.
Why do I sometimes have to use "GET / HTTP/1.0 vs. GET / HTTP/1.1" to obtain the desired results on some web pages and not on others. I have even varied the format of the request line to look the like the following: "GET / HTTP-1.1" or "GET / HTTP 1.1" which has afforded me more consistent results on some web sites, whereas I perform the GET request utilizing HTTP 1.1 and I obtain the proper reply back from the remote host. Is there a format for the request line that would be consistent with the specification and yield consistent results? Any assistance that you can afford would be greatly appreciated!! Thank you very much!
Eric.

If you read a little farther in the HTTP spec, you'll see that the Host:
header is *required* by HTTP/1.1, and servers MUST reject requests that
don't have it. On the other hand, the Host: header is optional in
HTTP/1.0. If you found server that accept an HTTP/1.1 request without the
Host: header, then they are not really HTTP/1.1 servers.

Since neither of these are valid HTTP version strings, the server is being
kind to you and assuming you meant to say HTTP/1.0.
Your requests should look like this:
telnet www.example.com 80
GET / HTTP/1.1
Host: www.example.com
