wont server from Cache

[Caunter, Stefan]

Assuming your cache is hot enough, you should be able to keep things
going with this in recv

 

  if (req.backend.healthy) {

                set req.grace = 60s;

        } else {

                set req.grace = 4h;

        }

 

If your backends all go away, grace is what saves you, but you need the
cache to be well heated.

Subject: wont server from Cache

 

Hi folks,

 

So I sent this post few days ago, I have made some changes but still
cant get my varnish box to server content from cache even though it
looks like it is:

232  Client requests received

         130  Cache hits

           5  Cache hits for pass

          97  Cache misses

          99  Backend conn. success

           3  Backend conn. failures

          99  Fetch with Length

          15  N struct sess_mem

 

 

When I shut down the web server it gives me a 503 error.

 

Here is the copy of my vcl file with out the backend info..  Any and all
suggestion would be appreciated.

 

 

sub vcl_recv {

 

#set req.backend = bw;

set req.grace = 60m;

 

if (req.request == "PURGE")

            {if (!client.ip ~ purge)

                {error 405 "Not allowed.";}

            return(lookup);}

 

 

if (req.request != "GET" && req.request != "HEAD")

           {return(lookup);}

 

 

   if (req.http.Cache-Control ~ "no-cache")

           {purge_url(req.url);}

 

return(lookup);

 

}

 

 

sub vcl_hit {

 

  if (!obj.cacheable) {

      return(pass);  }}

 

sub vcl_fetch {

    if (beresp.status == 500 || beresp.status == 503 || beresp.status ==
504) {

            restart;    }

 

        set beresp.ttl = 600s;

        set beresp.grace = 600s;

 

        if (beresp.ttl < 300s) {

          set beresp.ttl = 300s;}

        if (!beresp.cacheable)

            {return(pass);}

        if (beresp.http.Set-Cookie)

            {return(pass);}

}
