JavaScript-based Anti-Crawler
After JavaScript-based anti-crawler is enabled, when a client sends a request, the server returns a segment of JavaScript code to the client to check whether the client is a normal browser. This function depends on the cookie mechanism and JavaScript parsing capability of the browser.
For details, see "How JavaScript Anti-Crawler Protection Works" in Configuring Bot Protection Rules to Defend Against Bot Behavior.
