Proxy Server Kya Hota Hai? सरल परिभाषा
Proxy server ek intermediary system hota hai jo aapke device aur internet ke beech mein kaam karta hai. Jab aap kisi website ya online service ko access karte hain, to proxy server aapki request ko apne through process karke destination tak pahunchata hai. Iska matlab yeh hai ki aapka asli IP address hide rehta hai aur website ko proxy ka IP address dikhta hai. Yeh technique privacy enhance karne, content filter karne, ya internet speed improve karne ke liye istemal hoti hai.
Proxy Server Kaise Kaam Karta Hai? कार्य प्रणाली
Proxy server ka basic workflow 4 steps mein hota hai:
- Step 1: User apne device se request bhejta hai (e.g., website open karna)
- Step 2: Yeh request pehle proxy server tak jati hai
- Step 3: Proxy server request ko verify karke destination server ko forward karta hai
- Step 4: Destination server response proxy ko bhejta hai, jo use user tak deliver karta hai
Is process mein, aapka network traffic encrypt bhi ho sakta hai aur geographical restrictions bypass kiye ja sakte hain.
Proxy Server ke Prakar: 5 मुख्य प्रकार
- Forward Proxy: General users ke liye, client-side se requests handle karta hai
- Reverse Proxy: Server protection ke liye, backend traffic ko manage karta hai
- Transparent Proxy: Users ko pata nahi chalta, often offices mein use hota hai
- Anonymous Proxy: User IP address completely hide karta hai
- High Anonymity Proxy: Advanced privacy, regularly IP change karta hai
Har proxy type ke alag security levels aur speed capabilities hote hain.
