Dear List, For the browsers that support XHTML we'll set the Content-Type as "application/xhtml+xml" otherwise we'll send the same XHTML document as Content-Type "text/html." Is the best way to do this like: AddDefaultCharset text/html SetEnvIfNoCase Accept "xhtml" ua_supports_xhtml=1 Header set Content-Type "application/xhtml+xml" env=ua_supports_xhtml Thanks, http://www.t1shopper.com/ PS. We'd consider using mod_negotiation to do this but we'd prefer not to make a HTML and XHTML of the same page. We're just going to make one XHTML document and send it to everyone. The browsers that don't support XHTML will just have to do their best. PPS. The recommended Content-Type for XHTML documents (which despite mixed support, is W3C's recommended language for mobile browsers: http://www.w3.org/TR/mobile-bp/#ddc ) is "application/xhtml+xml" but it's permitted to be "text/html." http://www.w3.org/TR/2009/NOTE-xhtml-media-types-20090116/#text-html --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
