cURL -x Use of HTTP Proxy Server Examples

There can be certain reasons a software developer may need to reach out to an HTTP Request using a Proxy Server, to name a few,

• For Testing or Debugging an API.
• To Bypass the Load Balancer.
• To Bypass the Network Restrictions

In such a case, we can make use of the -x option along with a cURL request. When the -x flag is used the request to the HTTP request is executed via the proxy server which acts as an intermediary server between the client and the website server.

Syntax:

curl -x <proxy_protocol>://<proxy_host>:<proxy_port> URL

Option/Parameter	Description	Example
