Hi My application has facility that any user can create a ticket from the intranet site.So upon creating a ticket he gives an email id .And I have to send mail back to this mail id giving created ticket’s information…My application is running on differnt ports (say 3000 and 3001 or example) Both for two companies…So as part of ticket creation email to be send to removed\_email\_address@domain.invalid(if it created from company 1 intranet), and similarly removed\_email\_address@domain.invalid it created from company 2 intranet…here removed\_email\_address@domain.invalid and removed\_email\_address@domain.invalid are text boxes eneterd by the user So where will I store the portion after @ (company1,company2) .Is it inside a global variable by reading it from a yml file?This I am doing to change code for second company…I think you understand the problem ``` And also one thing Suppose if I store it in a yml file can I call ``` this only once when I enter in to the controller …As far I undestod before\_filer is called = no of times specified action is called Thanks in advance Sijo ---

[http://agilewebdevelopment.com/plugins/application\_config](http://agilewebdevelopment.com/plugins/application_config) ‘application\_config’ eases project configuring by introducing yaml config file in RAILS\_ROOT/config folder and provides handful methods accessing config values based on current rails environment. So, you can have separate sets of configuration properties for each rails environment you use.
