How to Set A Proxy For Curl?

5 minutes read

To set a proxy for curl, you can use the following command line syntax:

1
curl -x <proxy_host>:<proxy_port> <url>


Replace <proxy_host> with the actual IP address or hostname of the proxy server, and <proxy_port> with the port number on which the proxy server is listening. Finally, replace <url> with the URL you want to access through the proxy.


For example, to set a proxy with IP address 123.45.67.89 and port 8080 for curl, you would use:

1
curl -x 123.45.67.89:8080 http://example.com


This will make curl send all its requests through the specified proxy server.

What is an anonymous proxy?

An anonymous proxy is a server that acts as an intermediary between a user and the websites they visit. It allows users to browse the internet while hiding their IP address and other identifying information, thereby preserving their anonymity.


When a user connects to a website through an anonymous proxy, the website only sees the IP address of the proxy server instead of the user's IP address. This helps in masking the user's identity and location, providing them with a certain level of privacy and protection against potential surveillance or tracking.


Anonymous proxies are commonly used for various purposes, such as bypassing internet censorship, accessing geographically restricted content, protecting sensitive data or personal information, and maintaining online anonymity.
