+# Django Request-Response Mastering
+
+This Django project demonstrates **mastering request and response handling**, including plain text, numbers, booleans, JSON, redirects, headers, cookies, query strings, form data, and JSON body handling.
+
+---
+
+## 🚀 Features
+
+### 1. Response Examples
+
+| Type | Example |
+|------|---------|
+| Simple Plain Text | `HttpResponse('Plane Text Response')` |
+| Number Response | `HttpResponse(str(10))` |
+| Boolean Response | `HttpResponse(str(False))` |
+| JSON Response | `JsonResponse({'Name': 'Raihan', 'age': '18'})` |
+| Redirect Response | `HttpResponseRedirect('/')` |
+| Not Found Response | `HttpResponseNotFound('Page Not Found')` |
+| Custom Status Code | `HttpResponse('Status Code', status=202)` |
+| Custom Header | `resp = HttpResponse('Plane Text'); resp['token']='784001'` |
+| Response Cookies | `resp = HttpResponse('Plane Text Response with Cookie'); resp.set_cookie('Text_Cookie','784001adf')` |
+
+> **Note:** Only one `return` statement is executed per view. Multiple `return` statements cannot all run in one view.
+
+---
+
+### 2. Request Examples
+
+| Type | Example |
+|------|---------|
+| Request Methods | `GET`, `POST`, `PUT`, `PATCH`, `DELETE` handled in `TypesOfRequest` |
+| Query String | Access via `request.GET.get('param_name')` e.g., `QueryString` view |
+| Custom Headers | Access via `request.headers.get('header_name')` e.g., `CustomHeader` view |
+| Form Data | Access via `request.POST.dict()` e.g., `FormData` view |
+| JSON Body | Access via `json.loads(request.body)` e.g., `RequestBody` view |

+
+## 📝 Notes
+
+- Use `@csrf_exempt` for POST requests during development/testing.  
+- Only one response can be returned from a view.  
+- Cookie names cannot have spaces; use letters, digits, underscores, or hyphens.  
+- JSON responses are best handled with `JsonResponse`.  
+- Query parameters and headers can be accessed via `request.GET` and `request.headers`.  
+- Form data can be converted to dict with `request.POST.dict()`.
