I am trying to specify a custom (ASPX) page to handle 404 errors.
I can't seem to do this with IIS because I use a port other than the default.
I have two versions of my site, one exposed (default port) and one on another port, for testing. I'm trying to do this in testing mode first.
If I do: http://www.mysite.com/notapage ... I get the IIS 404 error.
If I do: http://www.mysite.com:1234/notapage ... I get a Google error (I use Google Chrome) as if it cannot resolve my site even though http://www.mysite.com/ works.
Any ideas?
