Get HTTP Headers

What Are HTTP Headers and Why Do They Matter?

HTTP headers are vital components of the HTTP protocol, acting as the metadata for client-server communication. They play a critical role in:

• Optimizing Website Performance: Headers help manage caching, redirects, and compression.
• Ensuring Security: Headers like Content-Security-Policy and Strict-Transport-Security protect against cyber threats.
• Facilitating Content Delivery: HTTP headers dictate how content is transferred between the server and client, ensuring compatibility and efficiency.
