OK I am revising my original question as now it has boiled down to a specific problem.
I need to set my server to block requests coming to /loc* (loc1, loc2 .. locn) folder on the root.
Is this possible? (I cannot find any other way around this as the requests are coming from random IP addresses and going for different folders that all start with /loc)

I am getting these image requests to my live site. Hundreds of them every few minutes..
Who and why would do this and what should be the steps to take to deal with it. They seem harmless if I am not missing the point but they are flooding my log files..
The controller for path '/loc295/th_21e_shower052.jpg' could not be found or it does not implement IController.
