You cannot host ASP.NET files in Tomcat. Well ... you could theoretically write tons of plugins, but I doubt anyone ever explored this other than theoretical exercises.
What you can do is redirect requests for ASPX files from Tomcat to IIS. Therefore, if the browser requests index.jsp, this request is processed by Tomcat. And if the browser requests default.aspx, then when forwarding Tomat to IIS and the server on the ASP.NET website. This is commonly known as hosting the ASP.NET website behind Tomcat.
But the reverse (hosting the JSP website for IIS) is much more common, as you can let IIS handle the authentication parts, which is very good. The official page for this connection is here , but there are many other sites dedicated to this topic.
