.htaccess, mod_rewrite and duplicate slashes?

Question

Apache HTTP Server

Good afternoon, to remove duplicate slashes, I use a regular expression of the form:

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

But a problem arose, and it lies in the fact that this regular expression is not global, each block of slashes is processed by a separate pass, respectively, by a separate request, and the following parsley is obtained in the log:

127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET ////WAT////no////u//must/be////kidding/////me// HTTP/1.1" 301 269
127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET /WAT/no////u//must/be////kidding/////me// HTTP/1.1" 301 266
127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET /WAT/no/u//must/be////kidding/////me// HTTP/1.1" 301 265
127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET /WAT/no/u/must/be////kidding/////me// HTTP/1.1" 301 262
127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET /WAT/no/u/must/be/kidding/////me// HTTP/1.1" 301 258
127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET /WAT/no/u/must/be/kidding/me// HTTP/1.1" 301 257
127.0.0.1 - - [17/Jul/2013:12:23:04 +0300] "GET /WAT/no/u/must/be/kidding/me/ HTTP/1.1" 404 226

Can you please tell me if it is possible to replace all duplicate slashes within a single pass using .htaccess, and how?
PS Additional, bonus question: I couldn't use Apache to replace the duplicated slashes from the root without query. For example http://test.ru///////, it is not caught by a rewrite, no matter how hard I try. In the upper case, these slashes are removed during the internal Apache redirect, but not by rewriting, this can be seen from the second line of the log, in which it is clear that the slashes disappeared not only at the beginning, but also before “no”, which was done by mod_rewrite.

Answer 1

2 years have passed. Catch the solution:

# Редирект на страницу без многократных /.
RewriteCond %{THE_REQUEST} //
RewriteRule .* /$0 [R=301,L]

Answer 2

Option without crutches:

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

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

Answer 3

I'm no expert, but try something like this:

RewriteRule ^Simplify/(.*?)/{2,}(.*?) Simplify/%1/%2 [N,C]
RewriteRule ^Simplify/(.*?) %1 [R=301,L]
RewriteRule ^(.*?)/{2,}(.*?) Simplify/%1/%2 [N]

Answer 4

As a crutch, I can suggest redirecting requests in which there are two slashes in a row to a script (without the "R" flag), which will already clean up the URL and issue the correct redirect.

Answer 6

For posterity:
A slightly unexpected solution
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$ [NC]
RewriteRule ^(.*)$ $1 [L,R=301]
