Use web host and Python to redirect messages

I have a website hosting plan which allows me to run python code, I'm looking for a way I can send data to a hosted python file. example: "http://ift.tt/1NVO3rl"

and the data I send to that file, then gets redirected to another destination such as a home server.

Reason being, I don't want a direct connection as I can't guarantee a connection 100% of the time, and I want to set it up to have a acknowledgement system where if the data doesn't get to the destination, it will queue it up till it can successfully send it.

The code to resend it I can do. It's just how to send data to an online python file to react to it. Is it like GET/POST methods or something else?

I don't exactly need the direct answer, I'm good with a push in the right direction.

However if you had experience with this or can advise on something then please.
