So still working on a script for KODI. Was wondering if it was a good or bad idea to leave a socket open for feedback or even if its possible. Did some research on other remotes that use forums of Java scripting. Seems like there are two ways to get feedback from KODI. Some will ping the server on a set time interval such as every 5 seconds to receive feedback back from the server, others do seems to leave a socket open. So every time some thing changes on the server, the feedback instantly updates on the remote. Right now I am doing the ping method every 3 seconds and so far works good, got every thing I need done. Now just trying to clean things up and make it more efficient, seeing if there is a better way.

Thanks,
Mike

Depends on what the server supports. If this is a JSONRPC api then the transport is likely HTTP-based. This being said, if you use the HTTP 1.1 protocol and don't specify a close connection header

Connection: close

Then the server may choose to keep the socket open. In certain cases, you can pipeline (send multiple) requests over the same socket waiting for a response after each request but your code has to process the Content Length response header such that it knows how to break apart each message.

There are other protocols such as the CometD/Bayeaux protocol that SqueezeCenter uses which support registering for 'events' on the server and when something changes, the server will send an event across the socket. CometD sends 'chunked' responses. I had to modify the Philips HTTP Library to support handling these types of responses so I know it works.

I have never used Kodi so don't know if it support asynchronous events or the protocol that it uses.
