mod rewrite: http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html

Im sure thats not exactly correct, but that will get you thinking, AFTER you read that link.

yes, mod-rewrite, but how will I go about it? Would all necessary changes go on the .htaccess file? Should extra-path info be on or off? Can I do it so that BOTH mydomain.com/b2e/a/2005/9/20/bunnies and mydomain.com/b2e/bunnies will work?

if you read the link you would know that mod_rewrite uses the .htaccess, so yes to question 1.

I do not know how the extra path info setting would affect those changes. Try it and see.

You can do just about anything with mod_rewrite. Check my site -- even my search is cruft-free
