Facebook opengraph and AJAX content

I have an application with AJAX content and I want users to be able to share URLs where the conten开发者_运维问答t of the page is determined by the hash/anchor portion of the URL (the stuff after '#'). That is, I want to determine the values of the opengraph tags based on the hash portion of the URL.

Google has a mechanism for this: http://code.google.com/web/ajaxcrawling … arted.html

Does Facebook?

Thanks

Yes.

Facebook handles AJAX sites the same way Google does. URLs with a hashbang are replaced with the _escaped_fragment_ parameter.

Compare the following:

and

Be sure that the Open Graph information, such as the URL, matches up with what the real page. Otherwise, FB will error, as was the issue I had.

No.

Also, don't do this. Make users like a full url with any #s. You can use # urls for quick transitions in your site, but I recommend having a full non # url for each thing you want people to like.
