Generally, if the server identifies itself as IIS it will support regular old ASP. These sites will generally use VBScript, but they could use JScript. If the developer is really hard core, they could use any Active Scripting language. What's more, I wonder how many might still be using something like Chili!Soft ASP on Linux/Apache. (I'd expect it might be small enough to be negligible.) Our servers (and many others I know of) are IIS, so they will support ASP without announcing this to the world. They will also report yes to both ASP.NET and PHP unless we have notification turned off for some reason because both are available even though everything we are doing right now is in PHP. Even in my last job (same employer, different department) we had ASP, ASP.NET, PHP and ColdFusion available. Everything we wrote was ASP, but from time to time we'd get an app written in one of the other languages that someone wanted to host for their department and often we'd host it. For that matter, what about someone using Phalanger, Monologo, or the like to write PHP syntax inside .NET? :-) Andrew -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
