Server - client communication

[drayne]

Hi,

 

I need to make web site, which will get requests from users that log in and activate those scripts. But, the problem is that the server has to, when the script is activated,  send request to another PC with the static IP address.  Then, that PC should execute the script, send its results to server, and then the server will notice user who activated it (clicked on the link).

So, the main problem is that server - client (static ip) communication, when the server is the first who sends request, not the client.

 

Any instructions would be appreciated, thanks in advance.
