AWS Sigv4 Proxy

A proxy can be used for anonymous web surfing. After all, the connection is made through an intermediate server. And all the sites visited by the user will see the IP address of the proxy server, not the user himself. It can also be used to access resources that are only available to the citizens of a particular country.

To connect to the Internet via a proxy server, you need to configure your browser or operating system to use the proxy server. Here's a general guide for setting up a proxy server using a web browser:

1. Open your web browser.

2. Access the browser settings or preferences:
- On Windows: Click the three-dot menu in the top-right corner and select "Settings."
- On macOS: Click the Apple menu in the top-left corner, select "System Preferences," and click "Network."
- On Linux: Click the menu button in the top-right corner, select "Settings," and click "Network."
- On Android: Open the "Settings" app and tap "Network & internet."
- On iOS: Open the "Settings" app and tap "Wi-Fi."

3. Locate the proxy settings:
- On Windows: Under "Network," click "Proxy settings."
- On macOS: Click the "Advanced" button and go to the "Proxies" tab.
- On Linux: Click the "+" button to add a new proxy.
- On Android: Tap "Private DNS" and "Static IP address" under "Advanced options."
- On iOS: Tap "Configure Proxy" under the active Wi-Fi network.

4. Enter the proxy server address, port, and authentication details (if required):
- Proxy server address: Enter the domain name or IP address of the proxy server (e.g., http://proxy-server).
- Port: Enter the port number used by the proxy server (e.g., 8080).
- Username and Password (optional): If the proxy server requires authentication, enter the username and password provided by the proxy server provider.

5. Save the proxy settings and restart the browser.

In Android to disable the proxy, you need to go to "Settings", then - "Connection and sharing", then - to "VPN". And then just deactivate the item. Many phones also provide for automatic disabling of proxies and VPNs when the device is rebooted. That is, if the user is difficult to understand the settings of the gadget, then you can trivially restart it through a long press the lock button (forced reboot).

The main task of these two popular technologies is to provide security for the Internet user. Despite a certain similarity of tasks, they are performed absolutely differently. Proxy, although it allows you to remain anonymous and bypass blocked sites, it is still quite vulnerable, especially when it comes to untested services. VPN in this regard looks preferable, because thanks to end-to-end encryption it reliably protects information from the entry point to the exit point.

It means a proxy that has no access to the Internet. It is created using special software on the user's computer. Most often it is used to check the performance of the created site or web-application.
