Nginx server not redirecting properly - php

Question

I'm getting a 404 error in nginx, when I should be getting a redirection instead.
I come from Apache and this is the first time I play with Nginx.
I suppose it has to be a minor mistake that I'm overlooking.
This is the code:
server {
listen 80 default_server;
server_name localhost;
root /var/www/resizing/public_html;
index index.php index.html index.htm;
location ~ ^/(.*)/cache/(.*)$
{
try_files $uri #resize;
expires 4h;
}
location / {
expires 4h;
}
location ~ \.php(.*)$ {
#fastcgi_pass 127.0.0.1:8000;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index index.php;
include fastcgi_params;
}
location #resize {
rewrite ^/(.*)/cache/(.*)$ /resize.php?dir=$1&path=$2;
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
allow ::1;
deny all;
}
# Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
#location /RequestDenied {
# proxy_pass http://127.0.0.1:8080;
#}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
#error_page 500 502 503 504 /50x.html;
#location = /50x.html {
# root /usr/share/nginx/html;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# fastcgi_split_path_info ^(.+\.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# # With php5-cgi alone:
# fastcgi_pass 127.0.0.1:9000;
# # With php5-fpm:
# try_files $uri =404;
# fastcgi_pass unix:/var/run/php5-fpm.sock;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
For instance if I type: localhost/cache/150x200-0/originals/1.jpg I get a 404error.

The problem is that the URI is /cache/150x200-0/originals/1.jpg, and it isn't matched by the location ~ ^/(.*)/cache/(.*)$ in your configuration.
Correct location will look like (assuming the "dir" component is actually needed):
location ~ ^(/.*)?/cache/(.*)$ {
...
}
Note well that the same problem is present in the rewrite used in the location #resize.
