Web Based Computer Programming

[Jim Becker]

I'm hoping someone here has run into this. With over 1400 members, seems like somebody must have.

I am trying to do some interactive message switching between IE and a program running on a server. Using an xmlhttp object, I am able to send a block of XML to a server program that writes another block back to the sending program. I want to keep the server program running and do another message exchange with the same session on the server.

I want to do this to maintain a file lock. Anyone know how to do it or have another approach?
