Actually there are three problems with this:
- URL-encoded query parameters are not unescaped prior to the mod_rewrite match
- the content-type is not set
- CORS headers are missing
Here's my version:
<Directory /var/www/profile>
DefaultType application/json
Header set Access-Control-Allow-Origin: "*"
</Directory>
RewriteEngine on
RewriteMap unescape int:unescape
RewriteCond ${unescape:%{QUERY_STRING}} resource=acct:(.+)
RewriteRule ^/.well-known/webfinger /profile/${unescape:%1}? [last]
This passes all of the checks on http://webfinger.net/
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)
You need a / (unlike @aaronpk) because your RewriteBase is different. You should still have the \ to escape the ., i.e. you should use:
RewriteRule ^/\.well-known/webfinger /profile/%1? [L]
Otherwise the rule will match a small number of (probably harmless) spurious URLs, e.g. https://example.com/Awell-known/webfinger (note letter A): the . is a wildcard: escaping it means a literal dot.
