I type in the following in command prompt
and type the following as the request html header
GET / HTTP/1.1
If-Modified-Since: Mon, 19 Mar 2007 02:43:31 GMT
and sent, but it always return me http/1.1 200 OK and the entire webpage.
Is my syntax correct? Can somebody give me an example that will return http/1.1 304 modified with the correct syntax?
