title: .htaccess Redirect To Another Site's Homepage Only If URL Don't Exist
body: <p>So this is what I'm trying to accomplish, and I'll do my best to explain...</p>
  
  <p>Through the .htaccess file, I'm attempting to redirect all pages of one site to another site, but ONLY if the URL doesn't exist. If the URL exists, then do nothing. Load that URL. If the URL doesn't exist, redirect to the homepage of another site.</p>
  
  <p>So, going to www.johnny.com/boxing (no files) or even just www.johnny.com (no files) would redirect to www.johnpunches.com, since neither of those URLs work. And that would work for any URL on www.johnny.com that doesn't exist. It would simply redirect to the index page of www.johnpunches.com</p>
  
  <p>However, going to www.johnny.com/members (where there is a working directory) would actually go to that URL and not redirect, because the page exists.</p>
  
  <p>So, again, if the URL exists, then do nothing. Load that URL. If the URL doesn't exist, redirect to the homepage of another site.</p>
