Nginx rewrite – remove substring at the end of URL

"No input File specified" error is coming form php-handler. This means rewrite rule is working fine but some other line is not prefixing proper base_dir.

Try this...

Replace

rewrite ^\/abc\/(\d+)\/(\d+)\/(\w+\S+)$ abc.php?a=$1&b=$2&c=$3 last;

With

rewrite ^\/abc\/(\d+)\/(\d+)\/(\w+\S+)$ /abc.php?a=$1&b=$2&c=$3 last;

Please note / (slash) before abc.php in above line.

Also problem can be...

1. In location ~ \.php$ {} block. I hope u have one for sure in your full config :-)
2. There must be a line like - root /var/www/exmaple.com; in your config. If its in location \ {..} block, you may need to copy it to the location ~ \.php$ {} or move outside location \ {..} but inside server {..} block.

If you can paste your nginx config here, it will be easier to debug. :-)

You need to change the links inside your application to point to the CDN for static includes.

When you rewrite to an http location there's nothing nginx can do but redirect the browser (since the CDN is outside of nginx, and the browser needs to get the files from the CDN). You would have the same issue with Apache or any other URL rewriter, as the CDN is not an "internal" location to the web server.

One option might be the nginx subsitution module, which can replace content as it is delivered. But that doesn't handle regular expressions, and would slow down every request. It is better just to change your application's HTML to reference the CDN URLs directly.
