Heads up: When running as a server the program needs elevated privileges. It may be avoided by entering the following command as administrator:
1
 
netsh http add urlacl url=http://*:11000/EPASSaleToPOI/3.1/ sddl=D:(A;;GX;;;WD)
 
 
1
 
where :11000 is the default port. If listening to another port the command must be changed.
