### Checking Proxies with Authentication
To check a proxy that requires authentication you need to pass the login and password to the request.
This works on both SOCKS and HTTP proxies. Example:
```
checker.php?ip=137.116.76.252&port=3128&timeout=20&login=foo&password=bar
```

#### Checking SOCKS Proxies
If you are using version 1.2 you will also be able to check SOCKS4/5 proxies. In version 1.2 the proxy is checked for SOCKS by default after it has partially failed a check for HTTP (Connection reset error), however knowing for sure whether it is a SOCKS proxy you are about to check or no can minimise the time it will take to process.

localhost/checker.php?file=abc.txt&timeout=20
```

#### Update: checking multiple proxies with a POST request
To check multiple proxies with a POST request, you need to pass the following request body:]
```json
{
"timeout" : 20,
"proxy_type" : "http(s)",
"authentication" : true,
"proxies" : ["ip:port:login:password", "ip:port:anotherproxy:password"]
}
```
This supports authentication and SOCKS proxies, based on the checkSingleProxy function.

This uses multi-threading and hence instead of taking 200 seconds for 10 proxies
(20 secs timeout * 10 proxies), it will take roughly 30 seconds to finish.
