To specify the data of a proxy server in the Opera browser, you need to follow the algorithm below:

Open the browser.
Click on the Opera icon in the upper left corner.
Go to "Settings".
Select the "Advanced" option.
Scroll down to the "System" tab.
Click "Open proxy settings for computer".
Click on "Network settings".
Activate the "Use a proxy server" option.
In the tab that opens, specify the IP address of the proxy server. The address must be entered in the field of the protocol to which the proxy server belongs. You can get this information from your proxy provider. Click "OK" to save your settings.

The easiest way to set up a home proxy server is to install a router that supports this function. Then get the proxy data (provided by the service in which it is "rented") and enter it in the router settings. If there is no need for a common proxy (for all devices at once), then it should be configured separately for each device with the help of the utilities integrated in the OS for changing the connection properties.

Proxy autoconfiguration is a feature that allows a client to automatically discover and configure the settings required to connect to a proxy server. This is typically done using a configuration file or script that provides instructions on how to set up the client's proxy settings.

The most common format for proxy autoconfiguration is the Proxy Auto-Config (PAC) file. A PAC file is a JavaScript file that contains functions to determine the appropriate proxy server(s) to use for a given URL or network condition. When a client is configured to use a PAC file, it will automatically execute the PAC script to determine the best proxy server for each request.

Another format for proxy autoconfiguration is the Web Proxy Autodiscovery Protocol (WPAD). WPAD uses a Dynamic Host Configuration Protocol (DHCP) option or a Domain Name System (DNS) query to locate a configuration script (usually named "wpad.dat") that contains the proxy settings. The client then executes the script to determine the appropriate proxy server(s) to use.

Proxy autoconfiguration makes it easier for clients to connect to the correct proxy server without manual configuration, especially in large organizations or networks where proxy settings may change frequently. It also allows for centralized management of proxy settings, making it simpler to update or change configurations across the entire network.

Setting up a proxy server correctly involves choosing the right hardware, selecting a suitable proxy server software, configuring the server, and securing the connection. Here's a step-by-step guide to help you set up a proxy server:

1. Choose the right hardware: Select a server or computer with adequate resources (CPU, RAM, and storage) to handle the expected number of connections and data transfer rates. You may also want to consider using dedicated hardware or a virtual private server (VPS) for better performance and security.

2. Select proxy server software: There are various proxy server software options available, such as Privoxy, Squid, and PacketFence. Choose a software that suits your needs, considering factors like ease of use, performance, and compatibility with your operating system.

3. Install the proxy server software: Follow the instructions provided by the software vendor to install the proxy server software on your chosen hardware. Make sure to download the software from a reputable source and use the latest version to ensure security and compatibility.

4. Configure the server: Configure the proxy server software according to your requirements. This may include setting up the IP address, port number, and authentication methods (e.g., username and password, IP filtering, or HTTP authentication). You can also configure additional settings, such as caching, bandwidth limits, and access control lists.

5. Secure the connection: Ensure that your proxy server is secure by using encryption (e.g., SSL/TLS) and implementing firewalls or intrusion detection systems. Regularly update the software and apply security patches to minimize vulnerabilities.

6. Test the proxy server: Once the server is set up and configured, test its functionality and performance. Verify that it can handle incoming connections, forward requests correctly, and maintain the desired level of anonymity or security.

7. Share the proxy server: If you want to share your proxy server with others, provide them with the IP address, port number, and any necessary authentication credentials. Be cautious when sharing your proxy server, as it can expose your IP address and bandwidth to others, potentially leading to security risks or abuse.

There are special online services that use IP and HTTP connection tags to determine if a proxy is being used from your equipment. The most popular are Proxy Checker, Socproxy.
