Include sub-paths in redirect?
When this is set to Yes, the sub-directory or filename under the source
URL path will not be included in the redirect. For example, if you
redirected /google to http://www.google.com and a browser
accessed http://example.com/google/something , the destination URL
would still be http://www.google.com.
If No was selected in this example, the destination would be
http://www.google.com/something instead.
However, if Yes is chosen you can use the special code $1 in
the destination URL. This will be replaced by the sub-path or filename that
comes after the source URL path.
