Hello All,

I'm currently diving into the InternetOpenUrl command and was wondering if
I could

1) ask it the protocol (HTTP, FTP, GOPHER) it has just accepted (so I can
use the apropriate commands to each protocol (for instance : not trying to
retrieve HTTP headers on a non-HTTP connection)

2) Retrieve the file-size when the protocol is not HTTP (I tried FTP, but
would like to be able to do the same for the other protocols). I've tried
the HTTP_QUERY_CONTENT_LENGTH method as well as FtpGetFileSize, but both
return an error.

Regards,
Rudy Wieser

You can use InternetCrackURL to get the scheme of the URL you just
passed in.

I know, its what I have done previously. I can even simplify that by doing
just text-compare with "HTTP://", "FTP://" or "GOPHER://".

But that means I would be attempting to mimic a test in another command,
something that is quite hard to when you have no information about how that
other test actually works (which input it accepts : are those three the
*only* things I have to check for ?).

Thats why I was looking for a way to let the command itself tell me its
test-result/accepted protocol. I can assume that when a HTTP-headers
related command fails the returned data is non-HTTP, but that is than not
even certain either ...
