I think. Is not the url for the beacon him self rather than the url that the beacon has in their payload. Rigth? Some like: `https://example.com/ngx_pagespeed_beacon?url=https%3A%2F%2Finternal.example.com%2F` If that is the issue, I think that is rigth to have external.example.com in these url because in the pagespeed cache, optimized resources are stored with these url as part of the cache keys. In this: user request (https://example.com/) --> proxy (https://internal.example.com) --> origin server beacon need to update the pagespeed cache info for that page (https://internal.example.com) and don´t know nothing about (https://example.com/). But maybe I´m wrong here, maybe @jmarantz can tell some words for this ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
