I need to replicate the following Apache rewrite rules in Nginx config on Ubuntu 12.04. What is the nginx equivalent to :

RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
  • Whoever found this online and tries to copy-paste the suggested answers, beware if you're using a Virtualbox setup with custom ports. I had to change it to be e.g. rewrite (.*)//+(.*) $scheme://$host:4321$1/$2 permanent; where 4321 is the external port of the Virtualbox'd nginx my browser connects to. – aexl Nov 20 '17 at 21:53

I'd like to suggest this approach:

# remove multiple sequences of forward slashes
# rewrite URI has duplicate slashes already removed by Nginx (merge_slashes on), just need to rewrite back to current location
# note: the use of "^[^?]*?" avoids matches in querystring portion which would cause an infinite redirect loop
if ($request_uri ~ "^[^?]*?//") {
rewrite "^" $scheme://$host$uri permanent;

It uses the default behaviour of nginx — merging of slashes, so we do not need to replace slashes, we simply redirecting

I found kwo's response to not work. Looking at my debug log, this is what happens:

2014/08/18 15:51:04 [debug] 16361#0: *1 http script regex: "(.*)//+(.*)"
2014/08/18 15:51:04 [notice] 16361#0: *1 "(.*)//+(.*)" does not match "/contact-us/", client:, server: *.domain.edu, request: "GET //////contact-us//// HTTP/1.1", host: 

I found this worked for me:

if ($request_uri ~* "\/\/") {
  rewrite ^/(.*)      $scheme://$host/$1    permanent;

  • Reference link is what you need to check. Correct solution is in there. I will try to edit the answer. – Anup Nair Apr 30 '18 at 7:36

Try this:

merge_slashes off;
rewrite (.*)//+(.*) $1/$2 permanent;

There might be multiple redirects for slashes > 3 or multiple groups of slashes.

  • 'merge_slashes off' made no difference and resulted in no change. – Anup Nair Apr 30 '18 at 7:34

URL example.com//dir1////dir2///dir3 and more Try this it's working for me

merge_slashes off; location ~ ^(.*?)//+(.*?)$ { return 301 $1/$2; }
