Create a HTTP POST/GET Appender

I would like to have an HTTP GET/POST Appender so that certain levels (e.g. WARNING and above) will generate an HTTP request to a web service. This will allow me to further propagate the error in near real time.

I have been looking into creating this myself and I have a working example with still many features missing (e.g. authentication, https, rate limiting).

If you think this is a good idea, I am gladly willing to share my source with you.
