What is Content Gate?

A content gate is a bot mitigation technique that withholds page content from the initial server response, instead requiring client-side JavaScript execution to render the actual content. Automated scripts that parse raw HTML responses see an empty or placeholder page, while real browsers with JavaScript execution see the full content.

Switch's Content Gate uses document.write() to inject content only after JavaScript execution, effectively blocking scrapers that use simple HTTP requests (curl, wget, Python requests) or headless browsers that don't fully execute JavaScript. This is more effective than CAPTCHAs (which frustrate human users) and more reliable than IP blocking (which catches legitimate visitors).

Content gates are particularly effective against high-volume scraping operations, training data crawlers that don't render JavaScript, and basic automation scripts. They're less effective against sophisticated browser agents that fully execute JavaScript, which is why Switch combines content gating with behavioral detection.
