-This document describes the request size limiting middleware that protects the STAC Atlas API from excessively large requests. - -## Overview - -The `requestSizeLimitMiddleware` enforces limits on: -- **URL length** (including query parameters) -- **HTTP header size** (total size of all headers) -- **Request body size** (for future POST/PUT support) - -## Configuration - -Limits are configured via environment variables in `.env`: - -```env -# Request Size Limits -MAX_URL_LENGTH=1MB # Maximum URL length (default: 1MB) -MAX_HEADER_SIZE=100KB # Maximum total header size (default: 100KB) -MAX_BODY_SIZE=10MB # Maximum request body size (default: 10MB) -``` - -### Size Format - -Sizes can be specified in multiple formats: -- `1024` - bytes -- `100KB` - kilobytes -- `1MB` - megabytes -- `10MB` - megabytes - -## Default Limits - -| Limit | Default Value | Rationale | -|-------|--------------|-----------| -| URL Length | 1MB | Allows very complex CQL2 filter expressions while protecting against abuse | -| Header Size | 100KB | Sufficient for authentication tokens, custom headers, and metadata | -| Body Size | 10MB | For future POST/PUT operations (e.g., bulk updates) | - -## Why These Limits? - -### URL Length: 1MB -- **CQL2 Filters**: Complex filter expressions can be quite large when expressed in CQL2-JSON format -- **Multiple Parameters**: Users may combine many parameters (bbox, datetime, q, filter, etc.) -- **Safe Buffer**: 1MB is generous for legitimate use while preventing resource exhaustion - -### Header Size: 100KB -- **Authentication**: JWT tokens, API keys, session cookies -- **Custom Headers**: X-Request-ID, X-Forwarded-For, User-Agent, etc. -- **Tracing**: Distributed tracing headers can be verbose - -### Body Size: 10MB -- **Future-proofing**: Although current API only uses GET, we may add POST/PUT endpoints -- **Bulk Operations**: Potential future support for batch operations - -## Error Response - -When a request exceeds the configured limits, the API returns a **413 Payload Too Large** error in RFC 7807 format: - -```json -{ - "type": "about:blank", - "title": "Invalid Parameter", - "status": 413, -

Generate request ID -app.use(httpLogger); // 2. Log request -app.use(rateLimitMiddleware); // 3. Rate limiting -app.use(requestSizeLimitMiddleware); // 4. Size limiting ← HERE -app.use(express.json()); // 5. Parse body -``` - -### Size Calculation - -- **URL**: `Buffer.byteLength(req.originalUrl, 'utf8')` -- **Headers**: Sum of all header names and values plus separators (`: ` and `\r\n`) -- **Body**: Handled by `express.json({ limit: MAX_BODY_SIZE })` - -### Performance - -The middleware is extremely lightweight: -- URL size check: O(1) - just byte length -- Header size check: O(n) where n = number of headers (typically < 20) -- No body reading: Delegate to express middleware - -## Customization - -### Adjusting Limits for Specific Deployments - -For high-volume APIs with simple queries: -```env -MAX_URL_LENGTH=100KB # Reduced for simple queries -MAX_HEADER_SIZE=50KB # Reduced -``` - -For APIs with very complex CQL2 filters: -```env -MAX_URL_LENGTH=5MB # Increased for complex filters -MAX_HEADER_SIZE=200KB # Increased for extensive tracing -``` - -### Disabling Limits (Not Recommended) - -To effectively disable limits (use with caution): -```env -MAX_URL_LENGTH=100MB -MAX_HEADER_SIZE=10MB -``` - -## Security Considerations - -1. **DoS Protection**: Limits prevent attackers from exhausting server resources with huge requests -2. **Memory Safety**: Prevents OOM errors from buffering massive URLs or headers -3. **Network Safety**: Reduces bandwidth waste from malicious or misconfigured clients -4. **Defense in Depth**: Works alongside rate limiting for comprehensive protection - -## Monitoring - -Monitor these metrics to adjust limits: -- Number of 413 errors -- Distribution of URL lengths -- Distribution of header sizes -- P95/P99 request sizes - -If legitimate users frequently hit limits, consider increasing them. -
