Take the Agent Hunter version 3.1 as an example. First, select "system"> "parameter settings" to go to the "operation parameter settings" dialog box of the Agent Hunter. Select "verify data Settings" and click "add". The verification name can start at will. For the verification type, select the default "feature string ", enter a URL in the authentication address that can be used as the Authentication Proxy Server, here it is better to add the address of a foreign site, such as "http://www.yahoo.com ". If you use a Chinese website, the verified proxy may not be able to go abroad. Enter the content of the browser title bar when accessing the verification address page in the feature string, that is, <title> feature string </title>. You can use a browser to connect to the verification address, view the webpage source file, copy the content between <title> and </title>, and paste it. However, in some cases, you may not be able to find the source file of the webpage. In this case, you can use Google to search for the URL and then search for the webpage title bar in the webpage snapshot to obtain verification data. The principle of the proxy hunter verifying whether the proxy is available is: first, send a request to the IP address to be verified, and then search for the data returned by the IP address to see if there is a pre-configured verification string, if yes, this is an available proxy.
For Agent Hunter 3.1, you do not need to set verification data yourself. Because this version of the Agent Hunter has already provided several verification data, you only need to select one to use it directly.
