Firefly III Reverse Proxy

A browser configured for the HTTP protocol sends client requests not directly, but through a proxy server, which in turn sends them on its own behalf to the destination host. The proxy server here acts as a link between the computer and the requested resource, and the response it immediately sends to the client.

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.

To reset proxy settings, you can follow these steps depending on your operating system:

For Windows:

1. Press the Windows key + R to open the Run dialog.
2. Type "inetcpl" (without quotes) and press Enter. This will open the Internet Properties window.
3. Click on the "Connections" tab.
4. Click on "LAN settings" in the bottom right corner.
5. In the "Proxy Server" section, select "Automatically detect settings" and click "OK".
6. Close the Internet Properties window.

A DNS proxy, also known as a DNS proxy server or DNS forwarder, is a specialized type of proxy server that intercepts and processes Domain Name System (DNS) queries. DNS proxies are responsible for translating human-readable domain names into IP addresses, which are used by devices to access websites and other online resources.

DNS proxies act as an intermediary between a client (e.g., a web browser, operating system, or application) and a DNS resolver (e.g., an ISP's DNS server or a public DNS server like Google DNS or Cloudflare DNS).

It is recommended to use third-party programs that allow redirecting all traffic through a proxy server. For example, ProxyDroid, EveryProxy. It is not possible to use proxies through the regular menu. Although in phones from some manufacturers such possibility has been added.
