Excellent post by seomike over at Search Engine Watch forums on how to make your framed site search engine friendly. seomike, in this post, gives both the unix and windows method of converting a framed site into something the search engines will eat up and spit out to the searcher.
The thread started with a member who asked about creating doorway pages, in order to help his site, which uses frames, to rank well in the search engines. For the technical details, on how to convert the site into something that can be easily crawled by the engines, please check out this post.
