Dynamic Loading of Configuration From Database

Hi All, I am looking at dynamically loading configuration of rails app depending on a flag that is being passed to the app through the HTTP header. The config is stored in a database table. Depending on the value received in the header, a model will make a call to the db and load up the config into the session. Is this best practice for loading config from db? Does anyone have a suggestion for doing this a better way?

Thanks in advance,

John

More detail, please. You seem to have a strange situation.
