[squid-users] Access-Control-* headers missing when going through squid

[Dan Charlesworth]

Thanks Amos.

As far as I can tell the only device upstream of the proxy is a relatively basic gateway/firewall. I doubt it's capable of messing with HTTP headers (and loading the site directly, as opposed to using the proxy lets it load fine behind the same gateway).

I’ve attached the debug output you suggested. Looks like the headers in the browser are the same as what arriving and leaving the proxy?



Best,
Dan
