HTTP Headers
Web ScrapingDefinition
HTTP headers are key-value pairs sent with HTTP requests and responses that provide metadata about the communication. In scraping, headers like User-Agent, Accept, and Cookie are critical for successful requests.
How It Relates to CrawlForge
Proper HTTP headers make the difference between a successful scrape and a blocked request. Anti-bot systems check for missing or inconsistent headers as a signal of automated traffic. A real browser sends dozens of headers; a naive scraper might send only a few.
CrawlForge automatically sends realistic header sets with every request. Tools like fetch_url and stealth_mode include complete header profiles that match real browser behavior, reducing the chance of detection.

User Agent
A user agent is a string sent in HTTP request headers that identifies the client software making the request. Websites use it to detect browsers, bots, and scrapers.
Rate Limiting
Rate limiting is a technique used by websites and APIs to control the number of requests a client can make within a given time period. It prevents server overload and defends against abusive scraping.
REST API
A REST API (Representational State Transfer) is a web service architecture that uses standard HTTP methods to perform operations on resources. It is the most common API style for web services.
API Endpoint
An API endpoint is a specific URL where an API receives requests. Each endpoint performs a specific function, like retrieving data, creating records, or triggering actions.
