Absolutely.

This stuff is part of Web Connection today, although I've made the stuff that
makes this possible Public Domain in the wwIPStuff class. I'll eventually update
this stuff for the PD distribution as well and there will be an article in
FoxPro Advisor regarding this mechanism.

Currently, wwIPStuff supports HTTPGet and HTTP Post operations. I've build a
scheme into the class that allows transferring data files over the wire transparently.
It's clean and fast and takes about 10 lines of code on each end.

You still need to run a Web server so you still need something like Web Connectino,
Active Server, FoxISAPI or a server OCX, but the code that goes into it is really
lightweigth.

Smart client and smart server makes for great possibilities in distributed apps.

Of course, this will only get better once Active Documents arrive when you can
run VFP inside of the browser including the automatic download features and
built in data connection as VB does, but for VFP this is likely a while off yet.
