XHTML

XHTML in Non-Compliant Clients

    - The MIME type is 'application/xhtml+xml'.
      An alternate for browsers without XHTML support is 'text/html'.
      For Web administrators, the typical configuration for Apache httpd is:

          RewriteEngine on

          # If a browser cannot handle XHTML (e.g. IE7), serve it as HTML instead:
          RewriteCond %{REQUEST_FILENAME} "\.(?:xht|xhtml)$" [nocase]
          RewriteCond %{HTTP_ACCEPT} "!application/xhtml\+xml" [OR]
          RewriteCond %{HTTP_ACCEPT}  "application/xhtml\+xml\s*;\s*q=0([^.]|$)"
          RewriteRule .* - [passthrough,type=text/html]
