Refine Apache configuration for WebSocket handling and improve documentation

Browse Source 
This commit updates the Apache configuration to enhance WebSocket support by refining the <LocationMatch> directive. It clarifies the need for multiple LocationMatch blocks and ensures proper handling of WebSocket upgrades and fallbacks to HTTP. Additionally, it encapsulates header settings within a conditional block for better compatibility. These changes improve the server's ability to manage real-time communication effectively.
