 ## Middleware Components

-### 1. Logging Middleware
+### 1. Platform Context Middleware
+
+**Purpose**: Detect which platform (OMS, Loyalty, Main) the request is for
+
+**What it does**:
+- Detects platform from:
+  - Custom domain (e.g., `oms.lu`, `loyalty.lu`)
+  - Path prefix in development (e.g., `/platforms/oms/`, `/platforms/loyalty/`)
+  - Default to `main` platform for localhost without prefix
+- Rewrites path for platform-prefixed requests (strips `/platforms/{code}/`)
+- Queries database to find platform by domain or code
+- Injects platform object into `request.state.platform`
+
+**URL Detection Logic**:
+```
+Request arrives
+      │
+      ▼
+┌─────────────────────────────────────┐
+│ Production domain? (oms.lu, etc.)   │
+└─────────────────────────────────────┘
+      │ YES → Use that platform
+      │
+      ▼ NO (localhost)
+┌─────────────────────────────────────┐
+│ Path starts with /platforms/{code}? │
+└─────────────────────────────────────┘
+      │ YES → Strip prefix, use platform
+      │       /platforms/oms/pricing → /pricing
+      │
+      ▼ NO
+┌─────────────────────────────────────┐
+│ Use 'main' platform (DEFAULT)       │
+│ Path unchanged                      │
+└─────────────────────────────────────┘
+```
+
+**Example**:
+```
+Request: https://localhost:9999/platforms/oms/pricing
+↓
+Middleware detects: platform_code = "oms"
+↓
+Rewrites path: /platforms/oms/pricing → /pricing
+↓
+Queries database: SELECT * FROM platforms WHERE code = 'oms'
+↓
+Injects: request.state.platform = <Platform object>
+```
+
+**Why it's critical**: Without this, the system wouldn't know which platform's content to serve
+
+**Configuration**: Runs BEFORE VendorContextMiddleware (sets platform context first)
+
+### 2. Logging Middleware

+- Platform sites: `localhost:9999/platforms/{code}/` → specific platform

+## Multi-Platform URL Routing
+
+Wizamart supports multiple platforms (OMS, Loyalty, Site Builder), each with its own marketing site and vendor ecosystem.
+
+### Platform URL Structure
+
+#### Development Mode (localhost)
+
+| URL | What it serves |
+|-----|----------------|
+| `/` | Main marketing site homepage (`main` platform) |
+| `/about` | Main marketing site about page |
+| `/platforms/oms/` | OMS platform homepage |
+| `/platforms/oms/pricing` | OMS platform pricing page |
+| `/platforms/oms/vendors/{code}/` | Vendor storefront on OMS |
+| `/platforms/loyalty/` | Loyalty platform homepage |
+| `/platforms/loyalty/features` | Loyalty platform features page |
+
+#### Production Mode (custom domains)
+
+| URL | What it serves |
+|-----|----------------|
+| `wizamart.lu/` | Main marketing site homepage |
+| `wizamart.lu/about` | Main marketing site about page |
+| `oms.lu/` | OMS platform homepage |
+| `oms.lu/pricing` | OMS platform pricing page |
+| `oms.lu/vendors/{code}/` | Vendor storefront on OMS |
