Rate Limiting
Web ScrapingDefinition
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.
How It Relates to CrawlForge
Responsible web scraping requires respecting rate limits. Making too many requests too quickly can overwhelm a server and get your IP permanently banned. Rate limiting is also a common anti-bot measure that returns 429 (Too Many Requests) HTTP status codes.
CrawlForge tools automatically handle rate limiting by throttling requests and implementing exponential backoff when limits are hit. This means your scraping jobs complete reliably without manual intervention to manage request timing.

Proxy Rotation
Proxy rotation is the practice of cycling through multiple proxy IP addresses when making web requests. This distributes requests across different IPs to avoid rate limits and IP-based blocking.
Robots.txt
Robots.txt is a standard text file placed at the root of a website that tells web crawlers which pages they are allowed or disallowed from accessing. It is part of the Robots Exclusion Protocol.
HTTP Headers
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.
CAPTCHA Solving
CAPTCHA solving refers to automated techniques for bypassing CAPTCHA challenges that websites use to distinguish humans from bots. This includes image recognition, token-based solving, and browser fingerprint emulation.
