Varnish 4.0 - Default VCL

# # This is an example VCL file for Varnish. # # It does not do anything by default, delegating control to the # builtin VCL. The builtin VCL is called when there is no explicit # return statement. # # See the VCL chapters in the Users Guide at https://www.varnish-cache.org/docs/ # and https://www.varnish-cache.org/trac/wiki/VCLExamples for more examples. # Marker to tell the VCL compiler that this VCL has been adapted to the # new 4.0 format. vcl 4.0; # Default backend definition. Set this to point to your content server. backend default { .host = "127.0.0.1"; .port = "8080"; } sub vcl_recv { # Happens before we check if we have this in cache already. # # Typically you clean up the request here, removing cookies you don't need, # rewriting the request, etc. } sub vcl_backend_response { # Happens after we have read the response headers from the backend. # # Here you clean the response headers, removing silly Set-Cookie headers # and other mistakes your backend does. } sub vcl_deliver { # Happens when we have all the pieces we need, and are about to send the # response to the client. # # You can do accounting or modifying the final object here. }
