I just checked my Linux installation and hey, what do you know, it's not
there. In comp.programming (which is where I'm reading this), "portable"
means more than just "portable to Windows".

Excellent.

Yes, Justin, it's called "programming".  :-)

Start off with your base URL. Parse on the / character. This gives you
tokens http: (in your example), www.myserver.com, and folder.

Build a data structure that represents that relationship:

      www.myserver.com
            ^
            |
            |
            |
            V
          folder

This rather simple example doesn't explain things very well, but
basically you'd have each node pointing to an array of child nodes and
also to a parent node (with the server node itself having a parent of
NULL). That would enable you to build up a picture of the server as you
go.

Anyway, from that start, finding a relative path is trivial. Start at
the "current" directory - in your case, www.myserver.com/folder - and
parse, again on the / character. If you hit a . on its own, you can
discard it. If you hit on .. on their own, you need to go one place
nearer the root. If you hit a token terminated by a /, you need to
change into that directory (possibly creating a new node in your data
structure in order to represent it), and if you hit a non-empty token
not ending in / at the end, that's the file you're after.

It's really relatively simple, but also relatively interesting, and well
worth the exercise of programming for yourself.

I mean "portable" as in.. I want to make a Linux port of my
application.
Therefore, WinInet has to go... but I still haven't worked out how I
am going to replace 'InternetCombineURL' function from WinInet.
Surely this has been done so many times before so I'd rather use
someone elses implementation otherwise I'll have to write something up
myself.
