To bypass detection through request header disguise, an e-commerce platform's anti-crawler system can be tricked by mimicking legitimate browser requests. This involves modifying or forging HTTP request headers to make the crawler appear as a normal user. Key headers to disguise include:

  1. User-Agent: Mimic popular browsers like Chrome, Firefox, or Safari.

    • Example: User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36

  2. Accept-Language: Set to common language preferences (e.g., en-US,en;q=0.9).

  3. Referer: Simulate traffic from search engines or other pages (e.g., Referer: https://www.google.com/).

  4. Cookies: Include session or tracking cookies to appear authenticated.

  5. Headers like Accept, Connection, and Upgrade-Insecure-Requests: Match typical browser behavior.

Example: A crawler sends a request with:

GET /product/123 HTTP/1.1  
Host: example.com  
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36  
Accept-Language: en-US,en;q=0.9  
Referer: https://www.google.com/  
Cookie: session_id=abc123

For scalable and secure anti-crawler solutions, Tencent Cloud offers services like Web Application Firewall (WAF) and Anti-DDoS Pro, which can detect and block sophisticated scraping attempts by analyzing header patterns, request frequency, and behavior analytics. Additionally, Tencent Cloud API Gateway helps manage and secure API endpoints against abuse.
