Roundcube Community Forum

Hey there,
could anyone help me?
I'm trying to extend my roundcube installation with a deref-funktion like gmx have.
I found following solution for myself but's very unperfekt because it would not work with ssl-protected sites

first the things witch are inperfekt
-external solution
-no user orientated protection
-no functionality with ssl-sites (because of domain orientated protection)
-not skinable/not using the user-skins

must have (in my eys)
-more integration in roundcube
-user orientated protection
-100% neutral link for those browsers witch reffer the deref site (sound's lucky but opera reffer the site in all cases I try)

may have
-using the roundcube skin

now my first try (and external solution):

first change links
Original:
$convert_patterns[] = "/([\w]+):\/\/([a-z0-9\-\.]+[a-z]{2,4}([$url_chars$url_chars_within]*[$url_chars])?)/ie";
  $convert_replaces&#91;] = &quot;rcmail_str_replacement('<a href=\&quot;\\1://\\2\&quot; target=\&quot;_blank\&quot;>\\1://\\2</a>', \$replace_strings)&quot;;

  $convert_patterns&#91;] = &quot;/([^\/:]|\s)(www\.)([a-z0-9\-]{2,}[a-z]{2,4}([$url_chars$url_chars_within]*[$url_chars])?)/ie&quot;;
  $convert_replaces&#91;] = &quot;rcmail_str_replacement('\\1<a href=\&quot;[url]http://\\2\\3\&quot;[/url] target=\&quot;_blank\&quot;>\\2\\3</a>', \$replace_strings)&quot;;
Replace:
$convert_patterns[] = "/([\w]+):\/\/([a-z0-9\-\.]+[a-z]{2,4}([$url_chars$url_chars_within]*[$url_chars])?)/ie";
  $convert_replaces[] = "rcmail_str_replacement('\\1://\\2', \$replace_strings)";

  $convert_patterns[] = "/([^\/:]|\s)(www\.)([a-z0-9\-]{2,}[a-z]{2,4}([$url_chars$url_chars_within]*[$url_chars])?)/ie";
  $convert_replaces[] = "rcmail_str_replacement('\\1\\2\\3', \$replace_strings)";
than the solution for dereffering the links (not my own solution):
deref/index.php
function tpl ($template)
 {
  if (file_exists ('tpl/' . $template . '.html'))
  {
   include 'tpl/' . $template . '.html';
  }
 }

 function logfile ()
 {
  global $link_url;
  global $config;
  if ($config['log'] == 1)
  {
  $fp = fopen ('log/logfile.txt', 'a');
fwrite($fp, "$link_url");
fwrite($fp, "\n");
   fclose ($fp);
  }
 }

 $config['prcl'] = 'http';
 $config['time'] = 0;
 $config['log'] = 1;
 $link_url = urldecode($_SERVER['QUERY_STRING']);
 if ($link_url != '')
 {
 /* Not nessesary because roundcube change the links itselve)

 if (substr($link_url, 0, 7)!='[url]http://'[/url]) || substr($link_url, 0, 8)!='[url]https://'[/url] || substr($link_url, 0, 6)!='[url]ftp://'[/url]
  {
   $link_url = $config['prcl'] . '://' . $link_url;
  }
  */
  $link_head = $link_url;
  $link_time = $config['time'];
  logfile ();
  tpl ('page_redirect');
  exit ();
 }

 tpl ('page');
 exit ();
 
 ?>deref/tpl/page_redirect.html
global $link_head;
global $link_time;
?>
[/url]



[/url]

Code to protect the deref-funktion from extrenal use:
SetEnvIfNoCase Referer "^https?://domain.tld/" ref //will not work, because ssl don't reffer the source page
SetEnvIfNoCase Referer "^http://(www.)?domain.tld/" ref

Order Deny,Allow
Deny from all
Allow from env=ref
now I'd like to include all this directly in the roundcube installation so that links look like

http://www.domain.tld/roundcubeinstallation/?_task=def&url=http://external.tld/link

and the authentication is given by roundcube login (session)



I hope my intention is understandable and anyone could help me to include these function.


at least a simple sumerage of the functionality of this.
-the destination page is given in the url (?destination)
-dereferring by using meta refresh
-for browsers without meta refreshfunctionality site with link in it (like: "klick here to go to .... ")
-protecting deref from unknown users

why all this?
to Protect userdetails (linke e-mail-nr and so on) from other webmasters (on destinationpages)

Well, which of this information do you want to protect?
https://webmail.domain.tld/?_task=mail&_action=show&_uid=63555&_mbox=INBOX

I've been thinking about implementing some deref, but I didn't because I have no idea what to protect since there is no session or user related information in the URL.
