If you do not have a third party trace tool to trace access for you IIS server then use the log file (thanks to Walter Wong). At first I have under estimated the IIS log file. It becomes handy if you do not have any 3rd part tool installed. You just have to close and open the file to refresh the transaction log. It does give you information on every page access.
The location of the log file show in the picture below.
The sample of the log file as below.
