My site currently uses modrewrite and uses a rewritemap perl file to do lookups so essentially perl is doing the rewrite. Currently if I have category "House" with sub category repairs , the url would be [login to view URL] . I am goin to change this so I can change the name of the sub category to house repairs and end up with the same url /house-repairs . Links in the categories are currently as /house-repairs-linkname and this is how id like to be able to keep it with the change
