Communication with a webserver... Stefan??
 

Is it possible for a web server to communicate with a server? Specifically what I have in mind is a kind of staff control panel for the server that would let staff edit the items of players without having to log on client. Is something like this possible (it would need to have 2-way communication that isn't based on polling the webserver every few seconds).

Sockets broh.

You can use TSockets to bind a socket on the server and accept incoming connections but you cannot do this without Stefan first allowing the binding to take place. Perhaps your suggested application of it would not be entirely sensible though, it just seems like adding another attack plane to the server is not a good idea when RC already works well enough (what if someone gets access to your supposed control panel?) so you might need to come up with a more compelling use for it.

I do believe Zodiac is using TSockets for their uploading system.

Could make the site, but make it some randomly named site and only allow trusted staff like Manager Dev admin to know it..

Not in the sense I'm talking about. They're using a request-only polling system (the NPC-server asks for the list of uploads) rather than one where the webserver can actually speak to the NPC-server.

Security through obscurity is no security at all.

Nope.

I did something like this, it was dumb in the sense that the PHP server never sent out the request, except Graal requested the state from the PHP server every few seconds instead and parsed it, since I can't get TSocket enabled on Testbed without going through too much trouble and, yeah.

TSockets do the trick
