HTTP, HTTPS, Requests & Responses (Hinglish Mein) Series: Bug Bounty Zero se Hero 🦸 | Article #3 By HackerMD | 15 min read Hacker MD Follow ~8 min read · March 26, 2026 (Updated: March 26, 2026) · Free: Yes Aaj Kya Seekhenge? ✅ Internet actually kaise kaam karta hai — bilkul basics se ✅ HTTP kya hota hai — simple example ke saath ✅ Request kya hoti hai, Response kya hota hai ✅ HTTPS kya hai aur HTTP se kaise alag hai ✅ Status Codes — 200, 404, 403, 500 ka matlab ✅ Bug bounty mein yeh sab kaise kaam aata hai 💡 Kyun zaroori hai yeh article? Dost, agar tumhe HTTP/HTTPS nahi patatoh tum bugs dhundh nahi sakte। Yeh bug bounty ka backbone hai। Har vulnerability XSS, SQLi, SSRF, IDOR sab HTTP pe hi kaam karta hai! Pehle Ek Simple Example Se Samjho Socho tum ek restaurant mein gaye ho 👤 Tum (Customer) = Browser / Client 🧾 Waiter = HTTP Protocol 👨‍🍳 Kitchen = Web Server 🍕 Pizza = Web Page / Data Tumne waiter ko bola → "Ek pizza do" = REQUEST Kitchen ne pizza banaya → waiter ne laya = RESPONSE Bas yahi hai Internet ka kaam karna! 🎉 Tum browser mein google.com type karte ho → Browser ek REQUEST bhejta hai Google ke server ko → Google ka server RESPONSE bhejta hai wapas → Tumhare screen pe Google ka homepage dikhta hai! Internet Ka Poora Journey Step By Step Jab tum https://google.com type karte ho — actually 7 steps hote hain: Step 1️⃣ — URL Type Karo Tum type karte ho: https://google.com ↓ Step 2️⃣ — DNS Lookup (Phone Book) Browser poochta hai: "google.com ka address kya hai?" DNS Server jawab deta hai: "142.250.195.46" ↓ Step 3️⃣ — Connection Establish Browser Google ke server se connect hota hai Port 443 (HTTPS) pe ↓ Step 4️⃣ — HTTP Request Bhejta Hai Browser likhta hai: GET / HTTP/1.1 Host: google.com ↓ Step 5️⃣ — Server Request Process Karta Hai Google ka server request padta hai Sochta hai — "yeh Google ka homepage maang raha hai" ↓ Step 6️⃣ — HTTP Response Aata Hai Server bhejta hai: HTTP/1.1 200 OK Content: [Google ka HTML page] ↓ Step 7️⃣ — Browser Page Render Karta Hai Tumhe Google dikhta hai! ✅ HTTP Kya Hai? Bilkul Simple HTTP = HyperText Transfer Protocol Isko English mein todke samjho: HyperText = Web pages, links, images Transfer = Bhejne ka kaam Protocol = Rules ka set jaise traffic rules Simple bhasha mein: HTTP woh language hai jisme Browser aur Server ek doosre se baat karte hain Jaise tum Hindi mein baat karte ho to dono samjhte hain — waise hi Browser aur Server HTTP mein baat karte hain। HTTP Request Andar Se Kya Dikhta Hai? Jab bhi tum koi website open karte ho ek Request jaati hai। Yeh request kuch aise dikhti hai: GET /login HTTP/1.1 Host: example.com User-Agent: Mozilla/5.0 (Windows NT 10.0) Accept: text/html Cookie: session=abc123xyz Connection: keep-alive Isko line by line samjhte hain bilkul easily: HTTP Response Server Kya Bhejta Hai Wapas? Server ne request padhi ab jawab bhejta hai: HTTP/1.1 200 OK Content-Type: text/html Content-Length: 1256 Set-Cookie: session=newtoken456

Isko bhi samjhte hain: HTTP Methods Waiter Ko Order Dene Ke Tarike HTTP mein alag-alag methods hoti hain har ek ka alag kaam: 📖 GET → Sirf data maangna (page dekhna) Example: google.com open karna 📝 POST → Data bhejnا (form submit karna) Example: Login form submit karna ✏️ PUT → Poora data update karna Example: Profile completely update karna 🔧 PATCH → Thoda data update karna Example: Sirf naam change karna 🗑️ DELETE → Data delete karna Example: Account delete karna 👀 HEAD → Sirf headers maangna, body nahi Example: File exist karti hai ya nahi check karna ⚙️ OPTIONS → Server se poochna - tu kya kya support karta hai? Bug Bounty Mein Kaise Kaam Aata Hai? 💡 Real Example: Mujhe ek target mein mila ki /delete-account endpoint sirf POST accept karta tha — lekin maine GET request bheja toh bhi kaam kar gaya! Yeh tha ek HTTP Method Bypass vulnerability! Bounty mili! 🎉 Status Codes Server Kya Bol Raha Hai? Status codes woh 3-digit numbers hain jo server bhejta hai — inhe samjhna bahut zaroori hai: 2xx Success! Sab Theek! 200 OK → Request successful, page mil gaya ✅ 201 Created → Naya data create ho gaya ✅ 204 No Content → Request hui, kuch wapas nahi aaya ✅ 3xx Redirect! Aur Aage Jao! 301 Moved Permanently → Page permanently aur jagah chala gaya 302 Found (Redirect) → Temporarily doosri jagah bhej raha hoon 304 Not Modified → Page change nahi hua, cache use karo 4xx Tumhari Galti! Client Error! 400 Bad Request → Tumne galat request bheji 401 Unauthorized → Pehle login karo 403 Forbidden → Permission nahi hai tumhe ❌ 404 Not Found → Yeh page exist nahi karta 405 Method Not Allowed → Yeh method allowed nahi hai 429 Too Many Requests → Bahut zyada requests bheji, slow down! 5xx Server Ki Galti! Server Error! 500 Internal Server Error → Server crash ho gaya 💥 502 Bad Gateway → Server ka doosra server kaam nahi kar raha 503 Service Unavailable → Server busy hai ya down hai Bug Bounty Mein Status Codes Kaise Kaam Aate Hain? 🎯 403 mile? → WAF bypass try karo — shayad file exist karti hai! 🎯 500 mile? → Server crash hua — SQL injection possible! 🎯 200 mile unexpected jagah? → Sensitive file exposed ho sakti hai! 🎯 302 mile? → Open Redirect check karo! HTTPS Kya Hai? HTTP Ka Secure Bhai HTTPS = HTTP + Security (SSL/TLS Encryption) Ek story se samjho: HTTP Postcard Ki Tarah (Dangerous!) Socho tum apne dost ko postcard bhejte ho "Mera password: abc123" likhke Tum ✉️ ————————————————————> 📬 Dost Postcard open hai! Beech mein koi bhi padh sakta hai! 👀❌ HTTP mein bhi yahi hota hai sab data plain text mein jaata hai। Koi bhi hacker beech mein "sniff" kar sakta hai! HTTPS Band Lifafe Ki Tarah (Safe!) Tum 🔒✉️ ————————————————————> 📬 Dost Letter band lifafe mein! Sirf recipient hi khol sakta hai! ✅ HTTPS mein data encrypt hota hai — beech mein koi bhi hacker padh nahi sakta! HTTPS Kaise Kaam Karta Hai? SSL Handshake Yeh process 3 seconds mein hoti hai jab bhi tum https:// wali site kholta ho: Step 1: 👋 Browser → Server "Hello! Main HTTPS connection chahta hoon" Step 2: 🔑 Server → Browser "Lo mera Public Key (Certificate)" Step 3: 🔐 Browser → Server "Theek hai, main Session Key banata hoon aur tere Public Key se encrypt karke bhejta hoon" Step 4: 🤝 Dono ek hi Session Key use karne lagte hain Ab saara communication ENCRYPTED hai! ✅ Step 5: 🔒 Secure Communication Shuru! Har ek message encrypted hota hai HTTP vs HTTPS Side By Side Real HTTP Request Burp Suite Mein Kaisi Dikhti Hai? Yahi wo cheez hai jo tum Burp Suite mein dekhte ho jab intercept karte ho: POST /api/login HTTP/1.1 Host: target.com Content-Type: application/json Content-Length: 45 Cookie: PHPSESSID=xvz123abc { "username": "admin", "password": "password123" } Bug hunter ki nazar se yeh request dekho: 🎯 POST /api/login → Login endpoint hai! 🎯 Content-Type: JSON → API hai — test karna chahiye 🎯 username/password → Brute force? Default credentials? 🎯 PHPSESSID Cookie → Session hijacking possible? 🎯 HTTP nahi HTTPS? → Credentials plain text mein ja rahe! Bas ek request mein 5 potential vulnerabilities! 🔥 HTTP Headers Chhupe Hue Khazane Headers woh extra information hain jo request/response mein hoti hain bug hunters ke liye goldmine! Interesting Request Headers: Host: target.com → Virtual host attacks! X-Forwarded-For: 127.0.0.1 → IP spoofing bypass! Referer: https://evil.com → CSRF token bypass! Authorization: Bearer xxx → JWT token attacks! Content-Type: text/xml → XXE injection! Interesting Response Headers: Server: Apache/2.4.1 → Version info leak! 🎯 X-Powered-By: PHP/7.2 → Old version = vulnerabilities! Access-Control-Allow-Origin: * → CORS misconfiguration! Set-Cookie: session=abc → HttpOnly flag hai? Secure flag? X-Frame-Options: missing → Clickjacking possible! Practical Burp Suite Mein HTTP Dekho Chalo ab Kali Linux kholo aur actual HTTP request dekho! Step 1: Burp Suite Open Karo # Terminal mein: burpsuite & Step 2: Target Setup Free Practice Site https://httpbin.org # Yeh website specifically HTTP testing ke liye hai — legal hai! Step 3: GET Request Dekho 1. Burp Suite → Proxy → Intercept ON karo 2. Firefox mein jaao: https://httpbin.org/get 3. Burp Suite mein request capture hogi 4. Dhyan se padho — har line samjho! Step 4: POST Request Test Karo 1. Firefox → https://httpbin.org/post 2. Burp Suite mein request capture karo 3. Right click → "Send to Repeater" 4. Repeater mein request edit karo aur dobara bhejo! Bug Bounty Mein HTTP Knowledge Kaise Use Hoti Hai? Har ek vulnerability HTTP pe based hai dekho: 🔴 XSS → HTTP Response mein script inject karna 🔴 SQL Injection → HTTP Request mein SQL code dena 🔴 SSRF → Server ko HTTP Request karwana 🔴 IDOR → HTTP Request mein ID change karna 🔴 CSRF → Victim ke browser se HTTP Request karwana 🔴 Open Redirect → HTTP Response ke Location header pe attack 🔴 CORS Issues → HTTP Headers galat configure hona Matlab HTTP samjho toh sab kuch samjho! 💡 YouTube Resources — In Se Aur Seekho Internet kaise kaam karta hai — Animation youtube.com/shorts/rLcgjNUC9fA HTTP Request & Response Methods Hindi youtube.com/watch?v=sFt1584SLKY HTTP Protocol Cyber Kaksha youtube.com/watch?v=91ZPVXpeLaI Intro to Web & HTTP Hindi youtube.com/watch?v=OeqAhIozg8A Aaj Ka Homework! 1️⃣ Burp Suite open karo 2️⃣ https://httpbin.org/get kholo 3️⃣ Request intercept karo 4️⃣ Har ek header ka naam note karo 5️⃣ Response mein Status Code dekho 6️⃣ Ek POST request bhejo https://httpbin.org/post pe 7️⃣ GET aur POST request compare karo Ek bonus challenge: https://httpbin.org/status/404 visit karo — kaunsa status code aayega?
