hi,

the following regex won't split correctly for nginx 0.8.46 due to a bug
in the capture offset processing. The problem occurs when the URI is not
fully captured but contains elements which should not be subject to the
split.

fastcgi_split_path_info ^/services(/[^/]+)(/?.*)$;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;

the following patch fixes the problem. it would be great if it could be
integrated in upcoming releases.

cheers,

frank.
