That depends what type of parser you require. Google for htmltidy.

The W3C gives a fairly comprehensive specification for the HTTP
protocol on its website. In general, you accept a command line that
starts with "GET", "HEAD", "PUT" and so on, usually followed by the
URL path (like "/~user/index.html" or something similar) then usually
followed by something like "HTTP/1.1" then a CR and LF. After that
you have sub-commands like: "Connection : Keep-Alive\r\n" or "Cookie:
<...>\r\n" or "Content-Encoding: <...>\r\n" or "User-Agent: <...>\r\n"
and so on to give more information about the command. Its then
followed by an additional CR, LF and then possible content parameters
(encoded according to earlier parameters; typically www-url-encoding
or MIME if its a form post of some kind).

I've never written a HTTP server, only the client. But I cannot
imagine that its really all that difficult. There must be available
source out there somewhere.

For just the parser part, you don't need to go beyond string
comparisons. Regular expression parsers such as PCRE might help a
little bit, but I don't think that it makes a big difference.

If you want to do this in practice, I would recommend that you also
install Apache and Ethereal (both are available for the most relevant
operating systems.) That way you can observe the protocol response
for a real HTTP server.

He wants to parse HTTP responses, not the HTML that might be in
the body of the response. That is, this sort of stuff:

HTTP/1.1 200 OK
Date: Mon, 25 Feb 2008 22:06:32 GMT
Server: Apache/1.3.33 (Darwin)
Content-Location: index.html.en
Vary: negotiate,accep t-language,accept-charset

Start by learning to spell common English words, such as 'you' and
'are'. Also the personal pronoun 'I'. Then consider how to
punctuate. A long series of dots is not a period.

After you do all that you will have reduced your annoyance level.
