Hi,
I'm new to "force.com", and wanted to please ask whether this platform has anything equivalents to "java servlet filters".
Namely, whenever my force.com application serves an Http Request (be it by visualforce, page layouts, or even webservices) - I'd like to execute a piece of my own custom code, e.g. perform auditing in my legacy format.
I'd prefer to make it reusable and separate from the business code (like a java servlet filter that performs audition: I can easily attach it to any business application) .

Thanks very much
 

Hi,
I'm evaluating force.com, and wanted to please ask if it has a concept similar to Heroku "addons".
Namley if I have some legacy datastore, with legacy TCP protocol, legacy java driver, and legacy query language (not even relational). Could Apex be extended to invoke it, through my TCP protocol?
Or am I limited to the option of exposing it as REST/SOAP which Apex can consume?

Thanks
