Doug Anson / HTTPClient-SSL

Fork of the working HTTPClient adaptation using CyaSSL. This version adds a derivation of HTTPText called HTTPJson to emit JSON text properly. Additionally, the URL parser has defines that permit longer URLs to be utilized.

Fork of HTTPClient by wolf SSL

This is a fork of the working HTTPS/SSL library that contains two extensions:

- HTTPJson - a derivation of HTTPText for emitting JSON strings specifically. No JSON parsing/checking is accomplished - HTTPJson simply sets the right Content-Type for HTTP(S).

- Expanded internal buffers for longer URLs. This is set in HTTPClient.cpp and is tunable.
