-Implementing websocket support
-------------------------------
-
-Websockets is a technology for creating a bidirectional stream-based channel over HTTP.
-
-To run websockets through Varnish you need to pipe it, and copy the Upgrade header. Use the following
-VCL config to do so::
-
-    sub vcl_pipe {
-         if (req.http.upgrade) {
-             set bereq.http.upgrade = req.http.upgrade;
-         }
-    }
-    sub vcl_recv {
-         if (req.http.Upgrade ~ "(?i)websocket") {
-             return (pipe);
-         }
-    }
