htaccess - Remove multiple slashes after domain with encoded accented characters

Question

I can remove multiple slashes anywhere in URL using:

RewriteCond %{REQUEST_URI} ^(.*?)(/{2,})(.*)$
RewriteRule . %1/%3 [R=301,L]

But it doe

Answer 1

This rule should work for you:

RewriteEngine On
RewriteBase /

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(.*?)/+(/[^\s]+) [NC]
RewriteRule ^ %1%2 [R=302,L,NE]

This will do these redirections:

1. /////help => /help
2. /////héllo/////abc/////123 => /héllo/abc/123

Answer 2

anubhava's answer is the shortest but alternatively this one is also working:

RewriteCond %{HTTP_HOST} !=""
RewriteCond %{THE_REQUEST} ^[A-Z]+\s//+(.*)\sHTTP/[0-9.]+$ [OR]
RewriteCond %{THE_REQUEST} ^[A-Z]+\s(.*/)/+\sHTTP/[0-9.]+$
RewriteRule .* http://%{HTTP_HOST}/%1 [R=301,L,NE]
