An ASP hosting is a hosting supporting the Active Server Pages technologies, promoted by the Microsoft company. The ASP technology allows to generate dynamic pages "on the fly", using the widest functional capabilities. An ASP hosting requires usage of the Windows platform. Thus, an ASP hosting is usually more expensive than its alternative, the PHP/Unix combination.

Also, we should point out that ASP provides a heavier load on the server than PHP. However, some projects are more convenient to be performed with ASP, which makes ASP hosting more and more demanded-for.
