How can I test if a proxy works?
If you want to make sure that your proxies are working fine, you can do so in your computer's terminal with a command-line tool cURL. Type the one you need into your domain:port field:
> curl -U user:pass -x domain:port https://www.whatismyip.com/
For example, to test a proxy with any location and a fast rotating session:
>curl -U username:password -x proxy.proxeidon.com:10320 https://www.whatismyip.com/
