I want to be able to cache pages that have a cookie. Let's say I have a
cookie called "testcookie" that I set up with php.
If testcookie = 1 I want a page (cached), if testcookie = 2 it will have a
different page ( i want to cache it) , and like that N times. This is my
current varnish vcl
____________
vcl 4.0;
# Default backend definition. Set this to point to your content server.
backend default {
.host = "127.0.0.1";
.port = "8080";
}
sub vcl_hash {
hash_data(regsub(req.http.Cookie,"^.*?testvarnish=([^;]*);*.*$" , "\1"));
}
sub vcl_recv {
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't
need,
# rewriting the request, etc.
}
sub vcl_backend_response {
# Happens after we have read the response headers from the backend.
#
# Here you clean the response headers, removing silly Set-Cookie headers
# and other mistakes your backend does.
}
sub vcl_deliver {
# Happens when we have all the pieces we need, and are about to send the
# response to the client.
#
# You can do accounting or modifying the final object here.
}

Any idea? Thanks!
