From EzTools Software:
HTML Scripting Pages (HSP) is a clientside, ASP compatible scripting plug-in for Internet Explorer. HSP makes it possible to run ASP Web pages on any Windows PC without a Web server involved. You can run ASP pages in either Internet Explorer or the Microsoft Web browser ActiveX control. With HSP, you can code the same mixed HTML and VBScript Web pages, using the familiar ASP objects. The only difference is that it runs entirely on the client Windows machine--in a single DLL. Display dynamically generated HTML in your Windows apps in embedded Web browser controls. No personal Web server is required to be able to run ASP pages on Windows client machines. The HSP pluggable protocol is essentially an ASP webserver in a single DLL.
