Welcome to WebmasterWorld Guest from 126.96.36.199
I've seen lots of information about remapping directories to new directories, or specific pages to new page locations, but not remapping an entire site to one specific URL.
Can it be done?
If the reason for this action is that you need to put up a new site and test it on-line, then consider developing and testing your new site in a separate subdirectory or on a separate subdomain and switching over 'all at once' after you're finished testing, rather than taking your existing site down for the duration of the development project.
For more information on mod_rewrite and related subjects, see the documents cited in our forum charter [webmasterworld.com] and the tutorials in the Apache forum section of the WebmasterWorld library [webmasterworld.com].
Crazy, isn't it?
I'd like to do this with as little damage to our search engine ranking as possible. Will a temporary redirect be effective for this?
