5.17. Turning Directories into Hostnames
Problem
You want to migrate pathnames under a single hostname to distinct hostnames.
Solution
Use RewriteRule in httpd.conf:
RewriteRule "^/(patha|pathb|pathc)(/.*)" "http://$1.example.com$2" [R] RewriteRule "^/([^./]*)(/.*)" "http://$1.example.com$2" [R] RewriteRule "^/~([^./]*)(/.*)" "http://$1.example.com$2" [R]
Discussion
The first recipe redirects requests of the form http://example.com/pathseg/some/file.html to a
different host, such as http://pathseg.example.com/some/file.html, but only for
those requests in which pathseg is patha, pathb, or pathc.
The second recipe does the same thing, except that any top-level path segment is redirected in this manner.
The third recipe splits the difference, redirecting all “user” requests to distinct hosts with the same name as the user.
