So one of my clients uses Yahoo Hosting in a shared environment. Absolutely horrible, can't even upload a .htaccess file.
They have an option where you can setup custom error pages by uploading a a html file into the main directory with a specific name (ie 404 is e404.html). The problem is Internet Explorer does not redirect to this custom error page, but all other tested browsers do (ie: google chrome, safari). http://help.yahoo.com/l/us/yahoo/smallbusiness/webhosting/editors/editors-16.html
In Internet Explorer (tested ie7-ie9) the user is not redirected to this custom error page. Instead they are showen a IE 404 error page.
So how does this error page redirect work? and how can I get IE to work with it.
