Services | Dynamic Web sites
As a user selects an option on the web site the current page will be generated and updated there and then. For example you can select an option from a menu and a further choice will be shown immediately (without reloading the complete page). This is eveyr useful when selecting options that could have different outputs.
This compares against Static pages which remain the same each time the page is loaded.
A prime example is thr Search facility on happygolf.co.uk (click).
