Cache page with dynamic query string

[Hugues Alary]

You don't need to put the query string back and even if you do so, it won't
change anything.


         GET /promo.php?foo at baz.com                GET /promo.php
client -----------------------------------------------> Varnish
-------------------------> backend
                 /promo.php?foo at baz.com                        /promo.php
client <---------------------------------------------- Varnish
<-------------------------- backend

On the Varnish side, the url cached is promo.php.
On the client side, the url in the browser bar will stay promo.php?
foo at baz.com and you can access the query string, in javascript.
