When a user accesses my website, there is going to be an iFrame on a subdomain, on a different IP address. There are going to be multiple IP addresses for different subdomains, that essentially hold the same webpage. The URL of the iFrame page will be updated dynamically, depending on different webserver loads. The users will still be able to see the correct URL in browser, by messaging from iFrames, and updating URL via history API.What are the disadvantages? Is there any way to tell search engines to crawl the iFrame? What is wrong with this idea?
