vphantom commented on issue #1154: URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1154#issuecomment-764856757
I just dug a little deeper and actually ngx_pagespeed is removing all our custom headers from our responses, both those set with `add_header` and `more_set_headers`. This means when PageSpeed is enabled we lose STS, Referrer-Policy, X-XSS-Protection, Allow and even the Set-Cookie emitted by ngx_http_userid. We also lose ETag and Cache-Control (which were overwritten anyway) with `ModifyCacheHeaders off`. I can't believe we hadn't noticed that before today… 😕 Does nobody else in production need to set any header in Nginx? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
