Mod_rewrite & robots.txt

I wish to disallow indexing of a couple directories of a website that is using mode-rewrite.

Do I list the "real" directory folder names or the mode-rewriten names in the robots.txt for exclusion?

I am thinking the mode-rewrite names, but I want to make sure.

That depends.

If you still have links - either internal or inbound - pointing to the old URLs then you have to block those as well.

For starters, why not try a site:yoursite.com search on google and yahoo to see if they still have some of the "old" urls in the index

The site is under developement. There is no "old" urls.

I am kind of new to mode-rewrite... and usually want all sections of site listed, but we are creating a section of site that users can only see after filling in a form. That section I do not want listed in search results. So... that section I want to disallow in robots.txt.

Question being... to disallow the mode-rewrite version name directories (/topic/detail.html) of pages, or... to disallow the actual folders in my ftp list for those pages (/after-form/subject123id549087723ddsw/)?

Just disallow the url that you use on your pages

Use the rewritten version (that's the version that Google sees).

Thanks!
