问题
I'm trying to remove duplicate slashes from URLs. The following .htaccess rule:
RewriteRule ^(.+)//+(.*)$ $1/$2 [L,NC,R=301]
do NOT work for me on a URL such as the following:
http://www.mp7.org/?site=69.com\\\\\\\\\\\\\\\\
The .htaccess file
#### mod_rewrite in use
Options +FollowSymlinks
RewriteEngine On

This rule won't work for backslashes. You must add a similar rule with backslashes
RewriteRule ^(.+)\\\\+(.*)$ $1\\$2 [L,R]
If you want to replace backslashes with (forward) slashes, use this rule instead
RewriteRule ^(.+)\\\\+(.*)$ $1/$2 [L,R]
And to remove all back-/slashes at the end of the request
RewriteRule ^(.*?)[/\\]+$ $1 [L,R]
and the same when it is a query string
RewriteCond %{QUERY_STRING} ^(.*=.*?)[/\\]+$
RewriteRule ^.*$ $0?%1 [R,L,QSA]
When everything works as you expect, you can change R to R=301.
Never test with 301 enabled, see this answer

This is because of IIS server, and mainly almost certainly your site is urbanized in .Net .asp or . aspx You need to put into service one miniature script, when your server be given http or https demand it must Lcase(URL). If there are not a lot of pages, you can rename all within lowercase, modify all inner linking of WebPages to lowercase and after that appeal URL removal request in Google webmaster tools.
