∟Examples of HTTP 1.0 Requests and Responses

This section provides some tutorial examples of HTTP 1.0 requests and responses. Google and Wikipedia are still supporting HTTP 1.0 protocols.

Let's continue to try my Perl socket test program to send a simple HTTP 1.0 request to some other Web servers.

www.wikipedia.org used to accept my HTTP 1.0 request in 2009. But now it returns the 400 error too:

herong> perl SocketRequestResponse.pl www.wikipedia.org 80 \
   http_get.req http_get.res

herong> more http_get.res
HTTP/1.1 400
Server: Varnish
X-Varnish: 1060976594
X-Cache: cp1079 int
X-Cache-Status: int-front
Set-Cookie: WMF-Last-Access=... 
Set-Cookie: WMF-Last-Access-Global=... 
X-Client-IP:
Content-Type: text/html; charset=utf-8
Content-Length: 1789
Connection: close

<!DOCTYPE html>
<html lang=en>
<meta charset=utf-8>
<title>Wikimedia Error</title>
...

www.apache.org used to accept my HTTP 1.0 request in 2009. But it also returns the 400 error now:

herong> perl SocketRequestResponse.pl www.apache.org 80 \
   http_get.req http_get.res

herong> more http_get.res
HTTP/1.1 400 Bad Request
Server: Apache/2.4.18 (Ubuntu)
Content-Length: 226
Connection: close
Content-Type: text/html; charset=iso-8859-1

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not 
understand.<br />
</p>
</body></html>

My HTTP 1.0 request worked nicely on www.google.com since 2009 and until 2018:

herong> perl SocketRequestResponse.pl www.google.com 80 \ 
   http_get.req http_get.res

herong> more http_get.res
