So I'm creating a plug-in for Adobe After Effects. I want to establish connection between it and my server (for ex to send Ajax request for approving serial number, or just sending a short cut of a frame) how to do such thing?
Any materials, blog articles would be wary grate.
Intersting wuestion but it's got absolutely nothing to do with After Effects.
You want to contact a wholesale online store that specializes in such products. Kagi comes to mind. You pya a small premium for their services but you have laredya indicated you're not really suited for the task of marketing and handling sales and security all by yourself.
Unrelated to AE. You simply use the socket libraries of your operating system, Java etc. to send direct network requests. As David said, if it's just for selling stuff, you can find enough services that can handle it.
