Adding Supr urls to your site

Over the last couple months I had a chance to help create a great new product for Stumbleupon. lets create short urls, publish directly to Facebook and Twitter and gives you great tracking and statistics around them. also helps you get more traffic by making it easy to get your content in front of the Stumbleupon community.

Last week we launched our API which lets you integrate shorten and post functionality into any site or application. Today we are adding the ability to use your own domain for shortening. This lets you have urls like so your readers can know what domain they are going too before they click on the link.

Now down to the fun part installation.

Step 1, Sign up for

Just go to the homepage and sign up using suprjosh for the invite code (The code is good for 500 sign ups).

Step 2, install and configure the PHP re-director

I’m not going go over this in detail since instructions are already available from

Note: when installing the rewrite rule you’ll want to make sure its not catching any of your other pages, I put mine after all my custom rules and added a condition to check the given url wasn’t the name of a file or directory.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^[a-zA-Z0-9]{4}$ supr.php?supr=$0
RewriteRule ^supr_settings.json$ supr.php?check_install=$0

If your doing your URL rewriting in PHP you might want to handle the link detection there instead, but 4 character words with no extension aren’t too common.

Step 3, Test is out

Now that you are up and running any short url created on for your domain will be use your domain instead of for the shortening. If you ran into any problems let me know, I will see what I can do to help.

Details on how things work

  • The settings on your server tell if it has a redirector
  • If the redirector is enable all new urls for the matching domain are made with your domain
  • Requests go to your server and are picked up by the rewrite rule
  • The redirector on your server makes a call to the API which returns a domain redirection url, something like
  • The user is redirected back to and then forwarded to the correct page on your server

The double redirection at the end lets us collect stats and do the required setup for showing the Javascript version of the Stumbleupon toolbar.

  4. I am attempting to use the plugin for wordpress. I followed the instructions on: and the site ins sync’d, but when I create a new post nothing happens. I noticed that if I have the
    “Display option to customize posts to Twitter or Facebook when I add a new blog” checked and include the short url generated by that the posting appears on, but not on flickr! Need help. Do I need to altar htaccess file even though I am using wordpress plugin.

  6. In the results, the number of clicks on the shortened link is shown. What is the number in the dark blue button immediately below the number of clicks?
