Can I run classic asp on a Cassini web server?
I have a mixed website (classic asp and dotnet) ...
No, you can’t. Cassini only displays ASP.net pages.
Have you considered IIS Express ? It is similar to user instances of Sql Server Express in that it can be started and used without requiring administrative rights or changes to your code to serve it. This is the “user mode” version of IIS and thus fully supports the classic ASP, which will help in your scenario.
It is not integrated into Visual Studio (just like Cassini), but at some point it will have a patch for the tools.
Cassini starts from Visual Studio. If you have a solution containing ASP.NET and ASP, it will continue to work on Cassini. But you cannot run a purely classic ASP application this way.
