JENKINS-65905: ReverseProxySetupMonitor has broken referer de-/encoding

[yuezhuangshi]

I also encountered that problem.
I have a jenkins docker images based on 2.249.3, it works fine in my Macbook Pro but broken in my Redhat linux(Tips: Reserve proxy not correct).
After setting the System property stapler.trace to true and check the response headers, I found
MacBook Pro:

Stapler-Trace-001: -> evaluate(<hudson.model.Hudson@6ec35bae> :hudson.model.Hudson,"/administrativeMonitor/hudson.diagnosis.ReverseProxySetupMonitor/testForReverseProxySetup/http%3A%2F%2Fjks.local%2Fmanage")

Redhat Linux:

Stapler-Trace-001: -> evaluate(<hudson.model.Hudson@46170fb7> :hudson.model.Hudson,"/administrativeMonitor/hudson.diagnosis.ReverseProxySetupMonitor/testForReverseProxySetup/http:/jks.devops/manage")

I am curious why http%3A%2F%2Fjks.local%2Fmanage became http:/jks.devops/manage and how can I solve this problem?
