I have used ipipgo proxy service for several years to trip out of the experience of anti-blocking, today all dish out. Remember, this is not a textbook style set, are actually stepping on the pit for the wild way.

The three most damaging tricks of website IP blocking

Webmasters are so savvy these days that IP blocking is like a game of whack-a-mole. The first move is to look atfrequency of visitsThe second trick is to find out if there are more than 50 requests per minute from the same IP.trajectoryNormal users will not click on the product detail page at three o'clock in the middle of the night; the third move checkingIP qualityThe treatment of server room IPs and residential IPs is vastly different.

Guerrilla tactics with proxy IPs

If you want to not get blocked you have to learn guerrilla play, which at its core is eight words:Distribute fire, camouflage in place. Use ipipgo's pool of residential IPs, 90 million real home IPs to change at will. Here's a recommended killer combo:

Remember to add some random parameters in the request header, such as disguising the User-Agent as, "Mozilla/5.0 (Windows NT 10.0; rv:102.0) Gecko/20100101 Firefox/102.0″. This kind of detail done well, the success rate of anti-blocking is directly doubled.

IP quality is lifeblood

Anti-blocking must-kill three-piece set

1. Requests should be paced.：别用固定间隔，给请求加上0.5-3秒的随机
2. Traffic should be mixed with sand: Mix 1-2 irrelevant page visits per 10 capture requests
3. It's unusual to play dumb.CAPTCHA: Don't be a hard-ass, switch IPs and try again!
