**[Robert Scholte](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=rfscholte)** opened **[MNG-6413](https://issues.apache.org/jira/browse/MNG-6413?redirect=false)** and commented

The design of proxies doesn't match the with the real world anymore.
It is important that multiple protocols are supported, quite often handled by the same proxy. Also, the non-proxy is a global setting, not a per-proxy one.
