Vijay ne code optimize kiya, images compress kiye, par koi faida nahi. Phir Vijay ne hamara HTTP Header Checker tool use kiya. Result mein usne dekha ki header mein "Cache-Control" bilkul absent tha. Iska matlab server users ke phone mein website ki copy save (cache) hi nahi kar raha tha aur har baar naye sirrey se website load ho rahi thi. Hosting setting theek karte hi website 3x fast ho gayi!

HTTP Headers Ke Bare Mein Practical Tips
- Status Codes ko Samjhein: 200 ka matlab Sab Theek Hai. 301/302 ka matlab Redirection. 404 ka matlab Page nahi mila aur 500+ ka matlab Server ki galti hai.
- Security Headers: Agar aap ek e-commerce site chala rahe hain, toh headers mein "Strict-Transport-Security" aur "X-Frame-Options" zaroor hone chahiye, yeh hackers se bachate hain.
- Hacker log aksar header check karke pata lagate hain ki website kis technology (WordPress, PHP, Nginx) par bani hai. Security ke liye apne server configuration mein aisi extra details chupana (hide karna) behtar hota hai.
