HTTP: Don't let applications add Connection header to request

[Robert Shearman]

Hi,

I'm not entirely sure that this is the right place to put this as I'm 
not sure if we'd want to use the Connection header ourselves at some 
point, but it is a 2 line fix here and a 10 line fix elsewhere.

Changelog:
Don't let applications add Connection header to request.
