What potential security risks are associated with attempting to bypass a proxy server using PHP?

Attempting to bypass a proxy server using PHP can pose several security risks, such as exposing sensitive information, unauthorized access to restricted resources, and potential network vulnerabilities. To mitigate these risks, it is essential to properly configure and secure the proxy server to prevent unauthorized access. 

// Implementing a fix to prevent bypassing the proxy server
if ($_SERVER['HTTP_X_FORWARDED_FOR'] || $_SERVER['HTTP_X_FORWARDED_HOST'] || $_SERVER['HTTP_X_FORWARDED_SERVER']) {
    // Redirect to an error page or block the request
    header("Location: error_page.php");
    exit();
}
