not serving from Cache

[Vitaly Burshteyn]

Hi folks, thanks in advance.

 

So I have varnish running on 2.1.1 with the load balance feature that
works great.  Everything works, exept that if I shut down the backend I
get 503 erros.  Aka nothing is served from cache..

 

 

Any ideas as to what I am going wrong in my vlc file?

 

Thanks,

 

 

 

 

 

 

 

backend server1 {

        .host = "";

}

 

backend server2 {

        .host = "";

     }

 

director bw round-robin {

    { .backend = server1;    }

    { .backend = server2;    }}

 

 

sub vcl_recv {

set req.backend = bw;

if (req.url ~ "/") {

       unset req.http.cookie;    }

if (req.url ~ "\.(png|gif|jpg|swf|css|js)$") {

   return(lookup); }

 

    # Redirect requests to /admin/ to /oops/

    if (req.url ~ "^/admin/"){

    set req.url = regsub(req.url, "^/admin/", "/oops/");    }

 

    # Never cache this path

    if (req.url ~ "/affiliates/visa-signature/") {

        return(pass);    }

 

    if (req.url ~ "^/r/\d+/") {

        return(pass);    }

 

    # Don't cache if specific HTTP headers exist

    if (req.http.Expect) {

        return(pass);    }

    if (req.http.Authorization) {

        return(pass);   }

set req.grace = 60m;

}

sub vcl_fetch {

    set beresp.ttl = 120s;

    set beresp.grace = 200s;

 

   if ( beresp.status == 500) {

         set beresp.grace = 60s;

         restart;

     }

 

   if (req.url ~ "/") {

        unset beresp.http.set-cookie;

   }

 

 

if (req.url ~ "\.(png|gif|jpg|swf|css|js)$") {

   unset beresp.http.set-cookie;

}

 

    # Don't cache error pages

    if (beresp.status == 503) {

        return(pass);    }

 

    # Varnish will dutifully serve different objects for different
values

    # of "Cookie: foo" if "Vary:" contains "Cookie". We don't want this.

    if (beresp.http.Vary == "Cookie") {

        remove beresp.http.Vary;

    }

 

    # Anti-dogpiling feature - serve a stale request until a new one

    # can be fetched, for up to 30s

 

    if (!beresp.cacheable) {

       return(deliver);

       }

 

    return(deliver);

}

 

sub vcl_hit {

  remove obj.http.Set-Cookie;

}
