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

[Mike Franon]

Thank you!  I forgot about that...

so now my vcl looks like this and it works!!


Thanks again for the help.

sub vcl_recv {
if (req.url ~ "^/$" || req.url ~ "^/sample"){
                unset req.http.cookie;
                return(lookup);
}

else {
                return(pass);
}

}
sub vcl_fetch {
    if (req.url ~ "^/$" || req.url ~ "^/sample"){
        set beresp.ttl = 300s;
        set beresp.http.cache-control = "public, max-age = 300";
        set beresp.http.X-CacheReason = "varnishcache";
        unset beresp.http.set-cookie;
        return(deliver);
    }
}
