If you really need to use HTTP, the Internet developers toolkit for G has
CGI enabled web server. Using CGI VIs, you can create a VI to return a HTML
page as a response to a browser connection. Then data can be transfered with
in the HTML page.
On the receving side, you can make a VI which brows to the URL of the above
VI and filter unnecessary HTTP protocol.
It is possible.
BUT, have you thought of using TCP VIs?
If you choose a set of TCP port to use for your application, it is usuallty
easy to ask the network administrator to
open ports on his/her firewall
for the application. Yes, with TCP, the implementation is not easy as the
DataSocket. Nevertheless, DataSocket is a trouble if it have ot passthrough
a firewall.
For the project I am currently working, I used DataSocket VIs at the early
stage. However I could not find out what TCP (or may be UDP) ports they were
using and now using CGI based application with the toolkit.(Not completed
yet.)
