Hi Borden It's unclear from your email what you are expecting mod_rewrite to do. In particular, you talk about <img> tags, but mod_rewrite does not alter the HTML that is output, it alters the URL requested so that it can be mapped to a different resource. You mentioned three different URLs presented in the HTML, all of which have very different meanings: //www.example.com/image.png (1) www.example.com/image.png (2) /www.example.com/image.png (3) (1) is a protocol independent URL. Your browser will use whatever protocol the page this is referenced in to request this URL, and connect to www.example.com and request the resource /image.png (2) is a relative URL. Your browser will take the protocol, host and URL of the page this is referenced in and append the relative URL. Eg, if the current page is http://foo.com/bar/, then your browser will connect to foo.com and request the resource /bar/www.example.com/image.png (3) is an absolute URL. Your browser will take the protocol and host of the page this url is referenced in and request the resource specified. Eg if the current page is http://foo.com/quuz/, then your browser will connect to foo.com and request the resource /www.example.com/image.png Can you try to explain what URLs you are receiving - check your access log - and what URL those requests should be rewritten to.
