hi there, this is my first enquiry on this forum i have been doing some work on search engine indexing when i came across this two methods of gateway pages registration IP delivery (where u reg the IP address instead of URL- i hope i am right if not please correct me) Agent Delivery ( i could not understand this method) they seem to be methods of hiding data from the browser so they cannot actually find out how the website was designed. could someone give me a more clearer information on this.
I suspect that what you read about was discussing cloaking, a method of serving a page designed to rank well on search engines to spiders that come a-calling, and serving your normal human page to human visitors.
The discussion was likely about different methods to determine whether the visitor is a spider or a human, and hence which page to serve.
Each browser visit includes numerous headers. Using the user_agent header to choose which page to serve is commonly referred to as agent delivery, using the IP address header is called IP delivery.
