Facebook wants you to use the `og:locale:alternate` meta tag to declare what languages your site is available in. Unforunetly instead of having a refrence in the tag when they want to use the alternate local they tack `&fb_locale=es_ES` to the end of the URL(or what ever language code they want). My problem is my site is static so I can't read this extra info easily so was woundering if there was a way in the .htaccess file to remap the url.

so 
`(.*)(?|&)fb_locale=(.*)` to `[first 2 letters of $3]/[everything but first 2 letters of $1]`

so 

`en/test.html?fb_locale=es_ES`

should go to

`es/test.html`

```
RewriteCond %{THE_REQUEST} /([^/]+)/(.*)[\?&]fb_locale=([^_]+)_(.*) [NC]
RewriteRule ^ /%3/%2 [NC,L,R]

```

almost works but for some reason the value after ? still gets appended.
