How to bypass %23 (hash sign) through RewriteRule without data loss?

问题

I have the following .htaccess file:

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/command
RewriteRule .* /command/rewritehandler.php?q=%{REQUEST_URI} [B]

See specs at currently unanswered question https://stackoverflow.com/questions/29376788/mod-rewrite-directives-and-valid-invalid-utf-8-characters-after-first-character . If request to server the following /aaa%23%23aa then rewritehandler.php receives only /aaa. Looks like REQUEST_URI only handles data before %23. What I should type instead?

回答1:

Capture value from RewriteCond and then use a back-reference to make it work:

RewriteEngine On

RewriteCond %{REQUEST_URI} (.+)
RewriteRule !^command/ /command/rewritehandler.php?q=%1 [NC,B,L,QSA]
