I have an intranet of my department which we are planning to build in ASP. The server we would given to host it would be a linux box. I want to know if there is any way I can host ASP files on Apache without incurring extra cost (like using some other free web server for linux or putting support for ASP on apache).

You may be in for a rough ride if this site uses any COM+ packages. Enabe mod_perl and install this script in Apache.

no need to put extra cost...assign port number to apache server and perform url mapping , deploy asp files and host.

I believe you cannot use Linux box to run ASP, you may use PHP or JSP/ Servlets in a Linux box, but ASP I'm afraid you cannot. You can ONLY access an ASP created script from a Linux client box, via web server running in Windows, such as IIS or Apache (Windows version).

Strictly speaking, there may not be an exact solution for what you're asking, but here are some solutions that are close...

Grasshopper - Enables ASP.NET (not ASP Classic) to run as Java servlets on a Java webserver (Tomcat is a Java webserver)

ASP.NET on Mono - Although there are some patent intellectual property disputes, as it stands now Mono offers you the chance to run ASP.NET using practically any webserver on Linux.

Chilisoft - A special Java server from Sun that will run ASP Classic

ASP on Apache - Not sure why you might prefer Tomcat over other public licensed webservers, but Apache is an option this is just one of many solutions

I'd question your project specs to build using ASP - If that's what you know then fine but if you're building brand new I'd probably recommend a more modern architecture that would perform better like ASP.NET.
