Description

Cloned from Bug 2010138

Description of problem:
Subscription manager will send the following request to the Candlepin. This request has a "If-Modified-Since" header which is used to query if any certificate has been updated since the specified time. If no certificate has been updated, Candlepin will respond with 304 Not Modified status and empty data.

Satellite doesn't forward the header to the Candlepin causing Candlepin to return the certificate every time.
-------------------------------------
xx.xx.xx.xx - - [01/Oct/2021:17:07:39 +1000] "GET /rhsm/consumers/82b2ddaa-70ae-4ca8-9576-d8f31750caba/accessible_content HTTP/1.1" 200 6606 "-" "RHSM/1.0 (cmd=yum)"
-------------------------------------

This is causing subscription-manager to think that content access certificate has been updated on the server and then it will performs certificate and repos update locally. Because of this, subscription-manager sends a few redundant '/content-overrides' and '/release' calls to the Satellite.

Steps to Reproduce:
1. Register client to the Satellite with SCA enabled
2. Tail the foreman ssl access log

tail -f /var/log/httpd/foreman-ssl_access_ssl.log | grep "/rhsm"

3. Run yum repolist multiple times

Actual results:
Notice that '/accessible_content' api always return 200 status

Expected results:
'/accessible_content' api should return 304 Not Modified status
