read/custom and HTTP HEAD behaviour
[1/4] from: jmalv:hotm:ail at: 15-Feb-2002 9:42
I am trying to query a URL with HTTP HEAD but I get the full HTTP GET
instead
print read/custom http://www.yahoo.com reduce ['HEAD ]
or
response: copy ""
port: open tcp://www.yahoo.com:80
insert port rejoin [ "GET" newline "host:www.yahoo.com" newline "connection:
close" newline newline ]
while [ res: copy port ] [][ append response res ]
close port
How can I just get the HTTP HEAD without the full page ?
Thanks

Use "HEAD" instead of "GET" when opening the port. ie...

HTTP/1.1 200 OK

That works with rebol.com, anyway, though not with Yahoo. You may
need to supply more info in Yahoo's case, or it maybe it's just
because Yahoo refuses to supply just the header. But with a bit of
luck, it won't be Yahoo's header you're after. (:
