Rotating User Agents & Headers
Implement dynamic user agent and HTTP header rotation to mimic legitimate browser traffic and avoid detection.
Avoiding Detection
When you scrape websites, they often try to detect if you're a human or a bot. If they think you're a bot, they might block you!
One common way websites spot bots is by looking at your HTTP headers. These headers contain information about your request.
Understanding HTTP Headers
Every time your browser (or a script) makes a request to a website, it sends HTTP headers. Think of them as metadata attached to your request.
- User-Agent: Identifies your browser/OS.
- Accept: What content types you prefer.
- Referer: The previous page you were on.
- Accept-Language: Your preferred language.
