Which type of proxy connection requires the end-user to manually configure their browser settings?

The explicit proxy connection requires the end-user to manually configure their browser settings. In this type of setup, users must enter specific configuration details into their browser, such as the proxy server's IP address and port number. This gives users full control over the proxy settings, allowing them to direct their web traffic through the specified proxy server.

Explicit proxies are often used in environments where organizations want to enforce strict browsing policies, manage bandwidth, or provide an additional layer of security. Because the user must actively input the settings, it also allows for transparency, where the user is aware that their traffic is being routed through a proxy.

In contrast, other types of proxies, such as transparent or automatic proxies, do not require manual configuration by the user. Transparent proxies operate without user knowledge, intercepting traffic without needing any setup. Automatic proxies may use scripts or automatic configuration protocols to manage settings without requiring user intervention. This distinction highlights the explicit proxy's reliance on user configuration to function effectively.
