Hey, thanks for the replies - I understand more or less, but I'll try
to focus my question a bit -
1. the most important thing that I don't understand is the looks of my
back-end server:
HOW DOES IT WORK - "responding to requests of a Makerequest made by a
gadget"?
"replying to it by sending
information" ?
is there an example of a java server that does it, lets say? that I
can take a look at? I think that's what I need...
Because we want to do, let's say - a java server (that will be our
beck-end) that helps to manipulate and store all data
retrieved from the user using our gadget. How is it exactly all done
at this server?
I took a look here- http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
but it wasn't clear enough :(
Thanks,
Kogan.
