Bug ID: 45255
           Summary: Provide easy way to configure proxy (winecfg?)
           Product: Wine
           Version: 3.9
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: winhttp
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Currently wine tries to automatically detect proxy.

It will:

1) use env vars (http_proxy)
2) try to detect automatic settings (wpad)

One can easily disable env vars unsetting them or make them empty (since wine
3.9). However, there is easy no way to disable automatic detection without
directly editing registry (it is a binary entry) or installing IExplorer.

winecfg could have a tab or wine could have a new tool to set proxy settings,
just like windows control panel applet. However, it should have an extra
setting from what Windows already have: "Use system environment values".
