Host Headers

[xfreakart]

After some minutes of fight, I saw that if in a curl like:
(Purge for Varnish stuff)
curl -v -X PURGE -H "Host: www.xxxx.com" ....

from: *request.go
// For server requests Host specifies the host on which the
// URL is sought. Per RFC 2616, this is either the value of
// the "Host" header or the host name given in the URL itself.
// It may be of the form "host:port". For international domain
// names, Host may be in Punycode or Unicode form. Use
// golang.org/x/net/idna to convert it to either format if
// needed.
//
// For client requests Host optionally overrides the Host
// header to send. If empty, the Request.Write method uses
// the value of URL.Host. Host may contain an international
// domain name.

Bad -> req.Header.Set("Host", "www.xxxx.com")
Good -> req.Host = "www.xxxx.com"

At least in: go version go1.8.1 linux/amd64

Ah, so we need to add a special case for the Host header to set it differently. Noted, thanks!

PR welcome. ;) Been a bit busy with a conference paper deadline this week.
