[pmwiki-users] shared storage via http? and upload via http

[Stefan Schimanski]

So, here you are:

--------
class RemotePageStore extends PageStore {
  function RemotePageStore( $dir ) {
    $this->PageStore( $dir );
  }

  function exists($pagename) {
    if (!$pagename) return false;
    $pagefile = $this->pagefile($pagename);
    if( $pagefile ) {
      $f = fopen($pagefile, "r");
      if( $f ) {
        fclose( $f );
        return true;
      }
    }
    return false;
  }
}                                                                                                                                                                                                    
$WikiLibDirs[] = new RemotePageStore('http://test.1stein.org/remote-wiki.d/{$FullName}');
---------

And that's how it looks like: http://test.1stein.org/Remote/Test
And the proof:

    192.168.0.3 - - [26/Oct/2006:16:42:15 +0200] "GET /remote-wiki.d/Remote.Test HTTP/1.0" 200 540 "-" "-"
