HTTP/HTTPS Header Viewer 2.0

A simple and interactive JavaFX application that allows users to send HTTP HEAD requests to any server and view selected response headers. Built from scratch without using HttpURLConnection, this project manually handles HTTP and HTTPS connections using sockets and SSL.

How It Works

• The program parses the URL input by the user
• It decides whether to open a secure SSLSocket (for HTTPS) or a normal Socket (for HTTP)
• It sends a custom HEAD request to the server
• The response is parsed line-by-line, and only headers selected by the user are shown
• Headers are filtered using either exact name matching or regex
