Hi spirilis,
last days I was trying very hard to send a HTTP REST API call to a server via https.
The GET request was well formated and worked well from my PC. But when I sent the same request from my C3200 launchpad I got a "bad request" error 400 after a successful connect.
I started with your example code and adaped it with my host and URL.
Finally I found out that it only works when I split my URL with several parameters, in multiple client.print commands. It seams that there is someting wrong with the length of a URL. Maybe the URL will be trucated after an certain amount characters b
