Nginx rewrite en dash in url

nginxregexrewrite

I have URL:s which contain one en dash character like this:

https://domain.dom/path/document-–-name-contains-a-single-en-dash

I tried to create a rewrite to replace the '-–-' string (dash,en dash, dash) with a single dash like so:

rewrite ^(.*)-–-(.*)$  $1-$2;

…to achieve urls like so:

https://domain.dom/path/document-name-contains-a-single-en-dash

But this doesn't seem to work. What am I doing wrong?

The en-dash (assuming UTF8) is actually represented as three bytes in the URL. You can place arbitrary bytes into the regular expression by using the \x escape.

For example:

rewrite ^(.*)-\xE2\x80\x93-(.*)$ $1-$2;

NGINX Reverse Proxy – URL Rewrite

Any redirect to localhost doesn't make sense from a remote system (e.g. client's Web browser). So the rewrite flags permanent (301) or redirect (302) are not usable in your case.

Please try following setup using a transparent rewrite rule:

location  /foo {
  rewrite /foo/(.*) /$1  break;
  proxy_pass         http://localhost:3200;
  proxy_redirect     off;
  proxy_set_header   Host $host;
}

Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect.

Nginx: Rewrite/Redirect URLs in a subdirectory to root

Try:

rewrite ^/subdirectory(.*) /$1 last;

What you have requires a '/' after '/subdirectory'.

Also - a quick hack would be to make a symlink in the document root:

ln -s . subdirectory
