I have a site where I use dynamic subdomains but want it where if there is a 404 I want the viewer to go to the subdomain's main page, rather than the main 404 for the whole site (which is currently happening). Example: Site = www.XYZ.com Dynamic Subdomain = aaa.xyz.com If someone types in aaa.xyz.com/error.html (which doesn't exist) they go to www.XYZ.com/404.html I want them to go to aaa.xyz.xom/404.html For non-dynamic subdomains I know how to do that with .htaccess, but I don't know how for dynamic pages. Any method?
