Create automated Page Visits on Websites and uses proxies and has time delay settings

Looking for a simple desktop application where I can put in one or a list of website address in manually and as an uploaded .txt or .csv file. It will visit the home page for a random time period that I can set then look at other pages on that same website for a time period that I can set. I want to be able to set how many pages on the website it will attempt to visit also. It will randomly stay on the different pages for different time lengths that should be able to be set. If the website is no longer available then the software will keep track of that and flag the uploaded file which should be able to be exported from the software. If you can think of any other enhancements that would simulate website visits I am open to suggestions.
