A check answers three questions: does the proxy accept the login, what address does the request leave from, and where is that address. The simplest checker is one command that fetches a page which prints the visitor's IP.
A check tells you the proxy works in general. It does not tell you whether your target accepts it; only a request to the target does. Every BooProxies plan has a test button that runs the check from our side, which separates a problem with the plan from a problem with your setup.
Questions about proxy checker
What does a proxy checker test?
That the proxy accepts your login, what address the request leaves from, where that address is, and usually how long the answer took.
My proxy passes the check but a site blocks it. Why?
The check proves the proxy works, not that every site accepts it. That site distrusts the kind of address or the way your program behaves: try another proxy type, or slow down.

- 407 Proxy Authentication Required
- A 407 error means the proxy did not accept your login. The username or password is wrong, was cut short, or was never sent at all.
- Proxy latency
- Proxy latency is the extra time a request takes because it travels through a proxy before it reaches the website and comes back.
