varnish 2.15 - default set to cache nothing except two urls?

[Caunter, Stefan]

The difference is that in recv it is a "req" from the client. Unsetting
it "strips" the cookie, and makes the request cacheable.

 

In fetch it is indeed "beresp" (back end response), so you are
removing/changing HTTP headers from your web server. I've added a
max-age to control client browser behaviour in the example too.

Thank you for the help!

Quick question:

for this block

if (req.url ~ "/blah"){

                set beresp.ttl = 300s;

                unset req.http.set-cookie;

                set beresp.http.cache-control = "public, max-age = 300";

                set beresp.http.X-CacheReason = "Blah";

                return(deliver);

}

 

 

I thought it was unset beresp.http.set-cookie;

 

Is there a difference?

 

 

Thanks again.

You need in vcl_recv:

                unset req.http.cookie;

                return(lookup);

}

else {

                return(pass);

}

 

Setting 360s for beresp.ttl gets you 6 minutes J

 

Resetting it to 360 if it goes under 120 seems odd.

 

Use something like this in vcl_fetch:

 

if (req.url ~ "/blah"){

                set beresp.ttl = 300s;

                unset req.http.set-cookie;

                set beresp.http.cache-control = "public, max-age = 300";

                set beresp.http.X-CacheReason = "Blah";

                return(deliver);

}

HI,

 

I am fairly new to varnish, and was curious, is there a way to have all
traffic go through varnish to the backend without caching unless for
specific pages.  For example we only want two pages to be cached, our
home, and a specific page under the home as seen below?

 

Here is my default.vcl 

 

Thanks

 

 

 

backend default {

  .host = "127.0.0.1";   

  .port = "80";

}

 

 

sub vcl_recv {

 

    # for the default home page

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

        unset req.http.cookie;

    }

 

    

   # if they go directly to /samplepage

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

        unset req.http.cookie;

    }

 

}

 

sub vcl_fetch {

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

        unset beresp.http.set-cookie;

    }

    

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

        unset beresp.http.set-cookie;

    }

    

    

    #override cache headers from backend to keep element in cache for 5
minutes

    if (beresp.ttl < 120s) {

       set beresp.ttl = 360s;

  }

 

}
