Added WebFinger support to my email address using one rewrite rule and one static file.

[aaron@parecki.com www]$ cat .htaccess 
RewriteEngine on
RewriteCond %{QUERY_STRING} resource=acct:(.+)
RewriteRule ^\.well-known/webfinger /profile/%1? [L]

[aaron@parecki.com www]$ cat profile/aaron@parecki.com
{
  "subject": "acct:aaron@parecki.com",
  "links": [
    {
      "rel": "http://webfinger.net/rel/avatar",
      "href": "http://aaronparecki.com/images/aaronpk.png"
    },
    {
      "rel": "http://webfinger.net/rel/profile-page",
      "href": "http://aaronparecki.com/"
    },
    {
      "rel": "me",
      "href": "http://aaronparecki.com/"
    }
  ]
}

@roseeng According to the spec, the correct test URLs should use resource= instead of profile=:

• https://fmarier.org/.well-known/webfinger?resource=acct:francois@fmarier.org
• https://fmarier.org/.well-known/webfinger?resource=acct%3Afrancois%40fmarier.org

Right, I mixed up the url parameter and the folder name. Fixed.

I had to change the rewrite rule to this to make it work:

RewriteRule ^/.well-known/webfinger /profile/%1? [L]

(forward slash instead of backslash)
