    Since I haven't found a single topic on Varnish with Newscoop, here's my tweaked example,  if you can spot an error or have some suggestions, please don't hesitate to point them out. 





    /*
    * First, set up a backend to answer the request if there's not a cache hit.
    */
    backend default {

    .host = "host.hr";
    .port = "8080";
    }

    backend adserve {
    .host = "adserve.host.hr";
    .port = "8080";
    }

    /*
    * "receive" subroutine.
    */
    sub vcl_recv {

    # Use the backend we set up above to answer the request if it's not cached.
    set req.backend = default;

    # pass adserve
    if (req.http.host == "adserve.host.hr") {
    set req.backend = adserve;
    return (pass);
    }

    # exclude POST requests (on order for search to work).
    if (req.request == "POST") {
    ban("req.url == " + req.url);
    set req.http.X-Test = req.url;
    return (pass);
    }

    # fully exclude admin from caching, it could be pass, but since I had problems with sessions, I've tried pipe, still didn't fix the issue with random logouts, but it works
    if (req.url ~ "^/admin(.*)") {
    return(pipe);
    } else {
    return(lookup);
    }
    }

    sub vcl_miss {
    return(fetch);
    }
    sub vcl_hit {
    return(deliver);
    }

    /*
    * This is the subroutine which will fetch a response from the backend.
    */
    sub vcl_fetch {


    # lets try to modify cache control and see how it goes.
    set beresp.http.Cache-Control = "private, max-age=30, must-revalidate";

    # Get the response. Set the cache lifetime of the response to 20 secs.
    set beresp.ttl = 20s;

    # Indicate that this response is cacheable. This is important.
    set beresp.http.X-Cacheable = "YES";

    unset beresp.http.Vary;
    return(deliver);
    }

    /*
    * PIPE FIX for return(pipe) for admin.
    */
    sub vcl_pipe {
    # This forces every pipe request to be the first one.
    set bereq.http.connection = "close";
    }

    sub vcl_deliver {
    return(deliver);
    }
