Stands for Active Server Pages. ASP is a server-side scripting environment (not a scripting language) developed by Microsoft that allows embedding of scripting commands in HTML documents to create dynamic web pages. ASP is particularly useful for reading from and writing to databases in the background, and displaying the results on web pages. ASP comes with VBScript and JScript scripting engines, but third-party engines for Perl, REXX, and Python are also available.
