---------------------------------+---------------------------
 I've been trying to use the documented example () to setup a redirect for
 our website from http to https.  This documented example appears to only
 work in version 3.x and not 4.0 however.

 I've modified the example from:


 {{{
 sub vcl_recv {
     if ( (req.http.host ~ "^(?i)somesite.org" || req.http.host ~
 "^(?i)www.somesite.org")
          && req.http.X-Forwarded-Proto !~ "(?i)https") {
         set req.http.x-Redir-Url = "https://www.somesite.org" + req.url;
         error 750 req.http.x-Redir-Url;
     }
 }

 sub vcl_error {
     if (obj.status == 750) {
         set obj.http.Location = obj.response;
         set obj.status = 302;
         return (deliver);
     }
 }}}


 to:

 {{{
 sub vcl_recv {
   if ( (req.http.host ~ "^(?i)mysite.com") && req.http.X-Forwarded-Proto
 !~ "(?i)https") {
     set req.http.x-redir-url = "https://" + req.http.host + req.url;
     #error 750 req.http.x-redir-url;
   }
 }


 sub vcl_backend_error {
     if (beresp.status == 750) {
 #        set beresp.http.Location = beresp.response;
         set beresp.status = 302;
         return (deliver);
     }
 }

 }}}

 However, I'm struggling to figure out how to throw the custom error code
 to tell Varnish to go to the vcl_backend_error subroutine.  In reading
 through the documentation it seems like maybe I should use "synth" instead
 of "error" but this doesn't seem to be working for me either.  If I
 uncomment the commented out lines, I'm unable to restart Varnish.  Any
 ideas or help to do this?
