Serve resources from a consistent URL: facebook vs Google Pagespeed
facebook, facebook-like, google-pagespeed
Solution
If you want Facebook to load just one, you need to serve the containing page over https.
Here's a demonstration:
Visit:
Facebook site with HTTP
You'll notice it shows Serve resources from a consistent URL for xd_arbiter, now visit:
Facebook site with HTTPS
You'll notice Facebook only loaded the https version as we served the page over https. I'm not sure if this is a Facebook issue. It may be worth filing a bug with Facebook, you'll at least get some useful feedback, (I tried to but couldn't find out where you can file bugs for these things, http://developers.facebook.com/bugs/ seems inappropriate)
Edit: Updating broken links, Facebook seems to have fixed the original issue and these links no longer show the problem that they used to highlight.
Problem
There is a common problem on using Facebook like button or box, on using pagespeed online sevice by Google I get this : Serve resources from a consistent URL The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 25.3KiB. - http://static.ak.facebook.com/connect/xd_arbiter.php?version=7 - https://s-static.ak.facebook.com/connect/xd_arbiter.php?version=7 it is obvious that one is for secured ssl connection and other is for unsecured connection is there any possible way to make facebook load just one?
