There's two boxes in the iRules screen on the virtual, the left is "Enabled" -- these are actually configured on the virtual server. The right side is "Available" -- these are what are on the device and can be moved over to "Enabled."

 

You can reuse iRules on as many virtual servers as you want as long as they're written generically, such as an http to https redirect that uses the host header instead of hard coding the host into the redirect.

You can use the API with powershell, I'm a unix guy so I don't have any experience with it, but I bet there's a script you could modify in the codeshare somewhere. You'll at least need a read-only user to view it though, and more access to modify the virtual server to apply the iRule.

 

For the API call, there won't be anything under "rules" if it's not applied. To get a list of available rules, you'll just do a call to list all the iRules on the device, and then modify the virtual server and add the rule to it.
