is it posible to pass a parameter to an action in configuration time?

[Rodolfo García Esteban/CYII]

Hi,

I need to pass an url to an action for do some validations, this action is 
a parameter of application's configuration, the user mustn't modify it and 
it has the same value all the time. I don't know the best way to do this.

Thanks
