Can I read a remote file contents from an iRule?

Thanks for your responses guys.

This is how I have managed it so far - however I am always willing to try something different if this raises issues.

I have created an iFile which references a static file in /var/tmp and the iRule reads a value from here. I have a cronjob running every minute on a remote server which overwrites this file contents with a number of hits to a specific URI, and a cronjob running every minute on the LTM with modifies the iFile with this new file.

Its clunky, and not sure how it will perform in a production environment but mechanically it is doing what I need.
