 ### The CONNECT Method
 
-In HTTP/1.x, the pseudo-method CONNECT ({{!RFC7231}}, Section 4.3.6) is used to 
-convert an HTTP connection into a tunnel to a remote host. CONNECT is primarily 
-used with HTTP proxies to establish a TLS session with an origin server for the 
-purposes of interacting with "https" resources. In HTTP/2, the CONNECT method is

-similar purposes.

 A TCP connection error is signaled with RST_STREAM. A proxy treats any error in 
 the TCP connection, which includes receiving a TCP segment with the RST bit set,
