May I crawl the code from a Web page, but only for single users, and how do I make it available to all access users?

That is, for example: I open two pages at the same time (one is a Google is IE) to simulate two users if the first open Google will show a verification code (is the destination URL crawling over) but in the time of opening ie, this time IE's verification code will be Google's coverage of how to solve the problem for multi-user It's been bothering me for a long time, really hoping that God will solve
