Difference between Doorway Pages and Hallway Pages?

[system]

@Zorro D

Doorway page is that page which is very well optimized for high search rankings but when user clicks on that page, he will be redirected to another page.

In short, in this technique, a different page is displayed to search engine to that of user

Where as hallway page is a page having all the URLs of the website. You submit this page to search engine, when spider crawls it, all the URLs get indexed. It is a technique of fast indexing.

Does hallway page is like a sitemap of a website. i actually wants to see the page how the shape of a page is. can you give me a link where this action has been applied. i would love to see if you can plz plz plz
