I am using a bot to crawl some websites. How do I automate changing identity if a required page starts to redirect me to some other page for an excessive amount of traffic coming from "me" via AdvOR? Can I use some sort of error page rules, domain/url masks or maybe check for certain a string in the in the actual HTML coding of redirecting page? And should it suffice to change IP only? Thanks.
