[Aokromes]

Is your feature request related to a problem? Please describe. trying to use mubeng to connect to one page i needed few attempts to connect to target server, even the list of proxies was updated by one script on mubeng startup.

Describe the solution you'd like maybe a good idea can be show what's the proxy used of the txt to allow manually remove it.

Describe alternatives you've considered more strict checks of proxy "alive" status.
