Proxy server

A proxy server acts as an intermediary between a client requesting a resource and the server providing that resource. In simple terms, it receives requests from clients, forwards these requests to the target server, receives the server's response, and then forwards the response back to the client.

Prerequisites

• Node(Express)
• http-proxy(package)

Getting Started

1. Clone the repository.
2. Install all required dependencies.

     npm install express http-proxy nodemon

3. Run the server

     npm start

Testing the proxy server

we can test the working of proxy server with different methods:

Using Postman :

1. Open Postman.
2. Go to Settings (the gear icon in the top right corner).
3. Under the Proxy tab, enable the proxy and set the proxy server to localhost and the port to 3000.
4. Send a request to any URL (e.g., Click here).
5. The request should go through the proxy server, and you should see the response from the target server.
6. You should see the logs in the terminal like : Proxying request for: http://example.com . Which tells that the request is handled by your proxy server.

Using Web Browser :

For Chrome:

1. Go to Settings.
2. Search for proxy and click on Open your computer's proxy settings.
3. In the proxy settings, configure the HTTP proxy to localhost and the port to 3000.

For Firefox:

1. Go to Settings.
2. Scroll down to Network Settings and click on Settings.
3. Select Manual proxy configuration.
4. Set HTTP Proxy to localhost and port to 3000.

=> Open any website (e.g., Click here). The request should go through the proxy server, and you should see the response from the target server.
