    @markap14 I tested sending data using HTTP Site-to-Site with fresh build of 
this PR. It successfully sent data. The exception happens when a client sends 
data packet, but doesn't send additional data packet nor confirm the 
transaction. It seems Remote Process Group Port stop working in the middle..
    
    I've uploaded my [test flow template and 
nifi.properties](https://gist.github.com/ijokarumawak/03b781e5dea6e706421fdfabf4b30c8d).
 The flow should be the same as you mentioned. Would you take a look and let me 
know if there's any difference.

> We should add support for using HTTP(S) for site-to-site to be an alternative 
> to the current socket based approach.
> This would support the same push based or pull based approach site-to-site 
> offers now but it would use HTTP(S) for all interactions to include learning 
> about ports, learning about NCM topology, and actually exchanging data. This 
> mechanism should also support interaction via an HTTP proxy.
> This would also require some UI work to allow the user to specify which 
> protocol for site-to-site to use such as 'raw' vs 'http'. We also need to 
> document any limitations with regard to SSL support for this mode and we'd 
> need to provide 'how-to' when using proxies like http_proxy or something else.
