Hi, We at WGSN.com, the Worth Global Style Network supplying fashion information to businesses and students, are using mod_perl for user authentication. Users are authenticated against an Oracle database on an Apache caching proxy using Tim Bunce's DBI module (and Apache::DBI), and I cache the usernames in shared memory with Ben Sugars' IPC::ShareLite. Auth headers are re-written to reflect a users' group, and passed on to a content management system where content is served from. Thanks. -- Steven Cotton [EMAIL PROTECTED] [EMAIL PROTECTED]
