rewrite scheme for url redirect

Hi Sevy,

Not an nginx expert, but you say :

"rewrite ^/oldfolder/([0-9][0-9])([0-9][0-9])([0-9][0-9])_([0-9]).jpg$"

Shouldn't the rewrite be :
rewrite ^/oldfolderjpg/([0-9][0-9])([0-9][0-9])([0-9][0-9])_([0-9]).jpg$

Notice the oldfolderjpg instead of oldfolder. That would explain a lot...

Subject: rewrite scheme for url redirect

I'm going crazy with this since I can't get it working in any way...

I have a subdomain on a server, let's call it,
dedicated to serve images. Due to some bandwidth limitation i got a more
capable server so the webpages will remain on but the images
will be moved to

Since I had to change the names of images folders on the new server now
I need to rewrite the urls in order to fit my needs. Only the webserver
on runs NginX, so i need to do rewrite the original ruls
following a regular expression (regex) and do something like:

- The first and most logic rewrite scheme I tought about is:

rewrite ^/oldfolder/([0-9][0-9])([0-9][0-9])([0-9][0-9])_([0-9]).jpg$$1/$2/new_images/$1$2$3/$1$2$3_image_$4_large.jpg

permanent;But it didn't work (I really don't know why)

- The second way I tried out is:

location /oldfolder/([0-9][0-9])([0-9][0-9])([0-9][0-9])_([0-9]).jpg$ {
    rewrite ^$1/$2/new_images/$1$2$3/$1$2$3_image_$4_large.jpg

}And it didn't work either...

I tried this config too:

location ~ oldfolder/ {
  rewrite ^([0-9][0-9])([0-9][0-9])([0-9][0-9])_([0-9]).jpg$$1/$2/new_images/$1$2$3/$1$2$3_image_$4_large.jpg

}But with no luck...

After that I tried an old config cheme i used for another site (on the
same box) for a cdn config:

location ~ /oldfolder/([0-9][0-9])([0-9][0-9])([0-9][0-9])_([0-9]).jpg
  rewrite ^/(.*)$

}I've been triying in several ways but nginx keeps ignoring my rewrite
scheme redirecting to my default error image located at

Can anyone help me with this?

I'll write down my subdomain server config for your facility:

## ##

    server {
        listen       80;
        error_page  404;
        root   /home/sites/;
        }It's a very basic server config, that's why I can't understand
why nginx doesn't rewrite the images following such scheme...
