Hi, In a project we are trying to do some sanity checking on the URLs before they hit our CMS. We would like to make sure that a certain part of our REQUEST_URI matches a coresponding HTTP_HOST. For that we have two maps. One with HTTP_HOST and the URI-part, ie. host1.example.com uriA host2.example.com uriB ... And the other map with the opposite direction: uriA host1.example.com uriB host2.example.com ... We would like to make sure that a URL is always build up like http://host1.example.com/something/uriA/ or http://host2.example.com/something/uriB/ And if not a URL like http://host1.example.com/something/uriB/ should be redirected to http://host2.example.com/something/uriB/ Unfortunately we haven't come up with a usable combination of RewriteRule/-Cond/-Map. Any hints? Kind regards, Arne --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
