Hi there,
In order to save some time to people who might find this thread, here is
how to force mod_pagespeed to send a fully optimized version to varnish:
In your .vcl file:
sub vcl_recv() {
set req.http.X-PSA-Blocking-Rewrite = "whatever-you-want";
}
In your pagespeed configuration:
ModPagespeedBlockingRewriteKey "whatever-you-want"
It is worth noting that a feature meant to make reverse proxies like
varnish happy with mod_pagespeed is currently in beta, here is the relevant
link:
