Thank you for your response, Tom, You are correct in that I don't expect the server to alter the HTML output. I want to tell the server to fetch a file at an arbitrary path if it receives a request for an absolute URL. So, for example, say I have <img src="/example/path" />, I want to use a a rule in an .htaccess file to fetch the file at an arbitrary path, say "/prefix/example/path" or "prefix.url/example/path", etc. I do not want to change the global server settings, VirtualHost settings and/or raw web pages. Alternately, I want to be able to have a page with <a href="/example/path">link</a> and, when a user clicks on "link", be directed to an arbitrary location.
I forget that "//" denoted a protocol-independent URL, so thank you for telling me. Again, I can use rewrite rules to rewrite relative and protocol-independent URLs and get the file I want. However, even with error logging turned up to the trace8 level, I cannot see absolute URLs going into the rewrite rules in my .htaccess file. All I see, from access.log, is the server trying to fetch the file from the absolute URL (as you indicated in point 3 in your response) and returning a 404 error because there is no file there (which is why I want to rewrite it). I hope that's clearer.
