Jenkins / New Feature JENKINS-57708
Attempt to detect reverse proxy
Issue Type: New Feature New Feature
Assignee: Owen Wood
Components: support-core-plugin
Created: 2019-05-27 21:47
Priority: Minor Minor
Reporter: Owen Wood

We currently include Jenkins outgoing proxy info in the support bundle - https://github.com/jenkinsci/support-core-plugin/blob/master/src/main/java/com/cloudbees/jenkins/support/impl/UpdateCenter.java#L75

I'm proposing we try detecting reverse proxies as well.

A simple (but not bulletproof) solution is to look for the presence of the X-Forwarded-For header in responses to the configured Jenkins URL.

This solution would work for non-anonymous proxy servers.

Anonymous proxy servers would not include this header (by design).

Misconfigured proxy servers would potentially also not include this header.
