Hi all! Thanks a lot for your replies. I am still lost in getting an answer to this question: How do the links look like is mod_rewrite is off? Suppose the app name is .books. and url_prefix is q. Then, if mapping functions, one uses http://www.some- url.com/q/, and http://www.some-url.com/q/other/ calls the corresponding _q_index. How does it look like if no mapping is possible? Is it something like http://www.some- url.com/cgi- bin/books.other.cgi? And, is the final ./. indispensable for the root page? I would me much obliged for your help :) Greetings, Giorgi
