Is IISxpress compatible with Perl, ASP, ASP.NET, JSP, etc.?
Yes, essentially IISxpress does not care if the content of the response is static or dynamic. If, however the response already has transfer encoding or content encoding IISxpress will not attempt compression. If you are not sure look in the IISxpress Status window’s ‘History’ tab while you are running a browser session to see what is going on.
