Re: Does a web page exist

Couldn't the new SQL function HTTPHead work for this without installing
HTTPAPI? V6R1 forward.

Brad,

http_String() will send you an *escape message if you get an HTTP response
code (other than 200) from the server.

So you'd do something like this:

monitor;
http_string('GET': 'http://the-url-etc');
// page was found.
on-error;
// page was not found (or another error)
endmon;

Or, if you want to distinguish a 404 code from another code you could do:

monitor;
http_string('GET': 'http://the-url-etc');
// page was found.
on-error;
http_error(*omit: httpCode);
if httpCode = 404;
// page was not found
else;
// another error
endif;
endmon;

Does http_string() return blank or something that you know the page
"doesn't exist" should the web site return an error HTTP response
code?

I'd use http_string(), it'd be a lot simpler than http_url_get_raw().

I'm guessing http_string() is something that was added sometime since
2012.
