+++ This bug was initially created as a clone of Bug #1585069 +++
Description of problem:
There is new RFE which implemented general http proxy for foreman(+katello)
BZ 1333595 (6.4 clone is BZ 1572304)
If you set the setting to valid http proxy then suddenly all katello pages (and even org edit) throws "403 Forbidden" at you !!! This ultimate breakage is caused by the fact that every request is now proxied, even between internal components and even requests to localhost !!!
Some requests cannot and must not be proxied, for example all katello pages requests candlepin (8443/tcp) going via proxy all is denied.
Unless you specify Satellite FQDN in "HTTP(S) proxy except hosts" which is really really tricky and wouldn't be obvoius to many CUs.
So please exclude Satellite fqdn and localhost by default from being proxied.
Either by listing them by default in "HTTP(S) proxy except hosts" or (for localhost most applicable) exluding them right away in http proxy code.
Version-Release number of selected component (if applicable):
@satellite-6.3.1-3.el7sat.noarch (6.3.2 Snap1)
foreman-1.15.6.43-1.el7sat.noarch
How reproducible:
deterministic
Steps to Reproduce:
1. Set HTTP(S) proxy (having exlude list empty = which is default)
2. Navigate to any Katello page
"403 Forbidden" keeps smiling at ya
Actual results:
really really tricky and not obvious to many CUs.
setting http proxy breaks product
Expected results:
setting http proxy doesn't break anything
VERIFIED.
@satellite-6.4.0-13.el7sat.noarch
foreman-1.18.0.18-1.el7sat.noarch
by two following manual reproducers:
A)
1. Set "HTTP(S) proxy except hosts" to list of all capsules (usually [SATFQDN])
2. Set "HTTP(S) proxy" (http://proxy.example.com:3128)
3. Navigate to any Katello page
>>> success, Katello page is rendered correctly, when except hosts settings contains list of all capsules
B)
1. Set "HTTP(S) proxy" to nonsense (http://nononoproxy.example.com:3128)
2. Create a docker compute resource http://localhost:2375>>> success, traffic to localhost is no more proxied
