Before putting your Squid Proxies to work, it's a good idea to run a few quick tests to make sure they’re functioning correctly. Whether you're using them for automation, data collection, or secure browsing, confirming that your proxies are active and routing traffic as expected helps prevent headaches down the line.


Online Proxy Testing Tools

For quick and easy verification, you can use online proxy testers to check connectivity, location, and anonymity level. These tools are ideal if you want a simple overview without installing anything.

These tools are especially helpful for confirming that your proxies are routing traffic correctly and appearing in the expected region. Simply paste in your proxy (in the required format) and see if it connects and hides your IP correctly.


Proxy Testing with Command Line (cURL)

If you prefer working in the terminal or need to test proxies programmatically, curl is a simple yet powerful way to verify proxy performance.

  • For IP:PORT (IP-authenticated proxies):
    • curl -x http://123.456.78.90:8800 https://ipinfo.io/ip
  • For username:password authentication:
    • curl -x http://user123:pass123@123.456.78.90:8800 https://ipinfo.io/ip

This command sends a request through your proxy to ipinfo.io, which will return the IP address being used. If the output matches your proxy IP, the connection is successful.

💡 Tip: Add -L to follow redirects or -I to only show headers if you're debugging behavior.


Browser-Based Proxy Testing

If you've already set up your proxies in a browser (as outlined in our browser setup guide), here’s a quick way to confirm that they’re working:

  1. Open your configured browser (e.g., Firefox or Chrome with proxy extension).
  2. Navigate to https://whatismyipaddress.com.
  3. Check the displayed IP address—it should reflect your Squid Proxy, not your actual IP.
  4. Optionally, compare with other IP-checking tools, like http://ip-check.net, to confirm consistency and anonymity.

This method is helpful for casual testing or confirming proxy behavior during real-time browsing.
