This script starts up a server (listening process) on port 8080, and waits for incoming. When a request is received, it tries to make a connection (open a socket for communication), and spawns a thread to handle it.
The "handling" thread grabs the first 4096 bytes and decodes it (assuming it is encoded as "UTF-8" data.
It then goes to one of 3 main handling methods based on the beginning of the decoded content:
(1) "GET /register_" -- handleRegistrationRequest
- If the request is valid, it either replies that the username is already used, or registers a new user.
(2) "ASBSVC" -- handleProxiedProvider
- If the request is valid, it pools the connection.
(3) Otherwise, handleProxiedConsumer
- If the request is in valid format, it looks further into the request for data, tries to forward the request to the service provider, and waits for a response from the service provider.
I'm guessing this is used as part of a switching system to route/handle requests from IP Phones or similar?
May I ask why you want it converted to PHP? One major issue you're going to run into is that Python has native support for threads, while PHP does not. There is a threading library available for PHP (pthreads), which I am familiar with, but if this is a high volume application/server (appears that it might be?), my thought is that a threaded PHP version wouldn't be nearly as stable. However, I'm confident I could get it converted for you in less than 10 hours.
