The short answer is "no". iRules are not allowed any file-system access for many reasons, speed and security most of all.

 

 

The longer answer is that you can write to a class via iControl, and then have the rule re-read the values from that class. This makes it possible to programmatically update the information that a given rule is operating off of. It's just not as simple as scping up a file.
