title: mod_rewrite - change URL case
body: <p>Is there any straightforward way to change the case of any URL using mod_rewrite? </p>
  
  <p>I thought this was pretty trivial... apparently not. </p>
  
  <p>Examples:</p>
  
  <p><a href="http://example.com/id" rel="nofollow noreferrer">http://example.com/id</a>
  to
  <a href="http://example.com/ID" rel="nofollow noreferrer">http://example.com/ID</a></p>
  
  <p><a href="http://example.com/id/123" rel="nofollow noreferrer">http://example.com/id/123</a>
  to
  <a href="http://example.com/ID/123" rel="nofollow noreferrer">http://example.com/ID/123</a></p>
  
  <p>and so forth. </p>
