Simplified VCL for Varnish

Issue

I would like to set up a local environment with Varnish to closely resemble what I have hosted. 

Resolution

If you're using Varnish, the following VCL file has helped some customers who are setting up local environments that closely resemble Acquia Cloud systems.

backend default {
   .host = "127.0.0.1";
   .port = "8080";
   .connect_timeout = 2s;
}
 
sub vcl_recv {
if (req.http.X-Forwarded-For) {
   set req.http.X-Forwarded-For = req.http.X-Forwarded-For + ", " + client.ip;
} else {
   set req.http.X-Forwarded-For = client.ip;
}
if (req.request != "GET" && req.request != "HEAD") {
   return(pass);
}
if(req.url ~ "^/cron.php") {
   return(pass);
}
if(req.url ~ "^/xmlrpc.php") {
   return(pass);
}
if (req.http.Authorization) {
   return(pass);
}
if(req.http.cookie ~ "(^|;\s*)(SESS=)") {
   return(pass);
}
return(lookup);
}

This is a basic example. If you have other needs or tests you want to perform, we suggest that you visit the VCL examples page, which includes several real-world examples of VCL that you can use for reference.
