Handle https proxy's CONNECT response

Browse source 
When using a https proxy, an extra HTTP 200 header will be generated.
So we can't rely on detecting the first http header.

$curlHeaders with https proxy:
"HTTP/1.0 200 Connection established  <-- the https proxy's response

HTTP/1.1 307 Temporary Redirect
...
"

See https://stackoverflow.com/a/34537988/889429

Fixes #34131
