I need to solve this problem have a web page that use AJAX. When invoked internally it works fine but when acceded from the outside (https), passing through an ISA the AJAX scripts don't work. Problem is that I have no experience with either and don't know where to start the troubleshooting. Is something that I have to be aware when using AJAX with ISA? Is there something that I have to install in the ISA server for AJAX to work?
