Proxy connection code

How to use it

1. Paste a proxy line in any familiar format: username:password@host:port, host:port:username:password or with the protocol at the start.
2. If the line does not specify a protocol, choose it in the list: HTTP or SOCKS5.
3. Enter the address you want to open and the language. The code appears right away — copy it with the button.

By default the example uses an address that returns your external IP, so you can see at once that the request goes through the proxy.

What the examples take into account

• Special characters in the password. The username and password are encoded in the proxy address, so characters like @ and : in the password do not break the line.
• SOCKS5 with name resolution on the proxy side. The examples use the variant in which the site name is passed to the proxy, so there is no DNS leak.
• Timeout. It is set to 30 seconds everywhere: short timeouts are often not enough for residential and mobile addresses.
• Required libraries. SOCKS5 in Python and Node.js needs an extra package — the install command is given in a comment.

If the code does not work

First test the line itself in the proxy checker: if the proxy responds there, look for the cause in your environment. The error code will tell you what is wrong — it is explained on the proxy error codes page. Detailed examples for individual languages are in the guides section.
