So I've got an arduino uno with a CC3000 shield attached and I want to push data to my Xively account: https://xively.com/develop/yS4XfViIIEEkB94MJ4zs However I get this error when I connect:

HTTP/1.1 411 Length Required

I understand that error 411 is a call for content length but I've alread declared this in my header and I still get this error. Any help would be greatly appreciated :)
The Content-Length value must be a sequence of digits. What you sent is a letter, so the server complained that it didn't get your header in the correct format.
Instead of:
Content-Length: z
Use:
Content-Length: 0
If you are actually including data in the body of your request, the length should be the number of octets in the encoded body.
