When it comes to deliver XHTML to various browsers, it seems that the tutorial [1], written by Dominique Hazaël-Massieux, "Content-Negotiation Techniques to serve XHTML 1.0 as text/html and application/xhtml+xml" (2003), still represents the state of the art. In a small paragraph, under the heading "Can I serve one resource with two distinct MIME-types?", he wrote: While it's theoretically possible, I don't know any way to do it without breaking some important aspects of HTTP (such as proxying, or the HTTP PUT method) - that is, the method I know using RewriteRules doesn't set headers such as ETag as it should. Because I did not fully understand the above, I tried to implement it (.htaccess, Apache 1.3.32): AddType application/xml .xml AddType application/xhtml+xml .html AddType application/xsl+xml .xsl RewriteEngine on RewriteBase / RewriteCond %{REQUEST_URI} \.html$ [NC] RewriteCond %{HTTP:Accept} !application/xhtml\+xml [OR] RewriteCond %{HTTP:Accept} application/xhtml\+xml\s*;\s*q=0 RewriteRule .* - [T=text/html;charset=utf-8,L] Be aware, because of a bug [2] you can't change anything else for the URI selected. If you do, you will lose the MIME-type you want to insert! To prevent this, I've added the L (last) parameter. This works for me without problems! Some advantages: - no renames necessary, thereby preserving the search engine index - no content-negotiation, supports both HTTP1.0 and HTTP1.1. - no duplicate content - easy testing on a per directory basis Manfred [1] http://www.w3.org/2003/01/xhtml-mimetype/content-negotiation [2] http://issues.apache.org/bugzilla/show_bug.cgi?id=36590 -------------------------------------- Manfred Staudinger Vienna, Austria
