Wrapping openid identities

[Marco Bonetti]

Antonio,

I think I see what you mean, now.

Assuming you are using the Apache webserver and virtual hosts, you 
probably want to look into mod_rewrite and set up a wildcard redirector 
in the Apache configuration file of your virtual server.

Something like this should do (please note: completely untested!)


  RewriteEngine on
  # match usernames containing lowercase chars and dots.
  RewriteCond %{HTTP_HOST} ^([a-z\.]+)\.my_server\.com$ 
 

  RewriteRule (.*) /%{DOCUMENT_ROOT}/path1/path2/?user=%1$1 [L]


You'll also have to set up your name server (DNS) to resolve wildcard 
domains, e.g.

*.my_server.com		IN	A 	ip.address.of.vhost

Hope this helps,
best,
