title: Access older revision of SVN repo via HTTP / mod_svn
body: <p>Using the mod_svn module for apache you can access the repository not onl via SVN client but also directly via HTTP using the same URL. You only get a plain directory listing showing the HEAD revision in such a case.</p>
  
  <p><strong>It is possible (may be via URL parameters) to access older revisions of the SVN repository if they has net been copied/tagged within the SVN?</strong> </p>
  
  <p>I know that there are 3rd party software that allows to do so like ViewCV or WebSVN but I am interested in how far you get with only a plain SVN repository accessible via mod_svn and HTTP(S).</p>
