Reverse proxy ek aisa server hota hai jo client requests ko aage backend servers par forward karta hai, aur phir un servers se response lekar client ko wapas bhejta hai. Iska use load balancing, security, caching, aur client-server interaction ko simplify karne ke liye hota hai.
Reverse Proxy ke Fayde:
1. Load Balancing: Reverse proxy multiple backend servers ke beech traffic distribute karta hai, jo server load ko balance karne mein madad karta hai.
2. Security: Reverse proxy actual backend servers ko client se chhupa kar rakhta hai, isse backend servers ki security badh jati hai.
3. Caching: Reverse proxy frequently requested content ko cache mein store karta hai, isse response time aur server load dono kam ho jate hain.
4. SSL Termination: Reverse proxy SSL/TLS encryption ko handle kar sakta hai, isse backend servers par se encryption ka load kam ho jata hai.
Kaise Kaam Karta Hai?
1. Client ek request bhejta hai reverse proxy ko.
2. Reverse proxy ye request backend server (ya servers) ko forward karta hai.
3. Backend server response wapas reverse proxy ko bhejta hai.
4. Reverse proxy ye response client ko wapas bhejta hai.
Real-World Example:
Agar tum ek website visit karte ho, to ho sakta hai ki tumhari request pehle reverse proxy server par jaye, jo phir actual web server se data lekar tumhe response de. Isse tumhari website faster aur more secure ban jati hai.
