Restricting access to specific subdirectories

Server NGINX
1

Hey all,

I’m a little stumped about what I’m doing wrong here. Basically I have
a
subdirectory that I want to restrict access to specific IP’s, otherwise
return a 403.

If I do the following (inside my server {} block):

server {
// normal processing code here
…

    location ~ ^/my_ws$ {
            allow   XX.XX.XX.XX;
            allow   XX.XX.XX.XX/24;
            deny   all;
    }

}

Hitting the following URL works as intended and I get a 403 if I try
from
anywhere other than the specified URL’s: http://www.mydomain.com/my_ws

However, if there’s anything AFTER that (i.e. my_ws/, my_ws/page2,
my_ws?parameter1, etc.) it allows them to proceed regardless of IP.

I’m sure it’s something required before or after the $, but I can’t
figure
it out.

Thanks in advance!

Justin

do you need a $ at all? It’s a placeholder for the end of the string,
and all you care about s the start??

Your problem is absolutely to do with the “$”, and if you don’t yet
understand regex well enough to fix it, have a read through a simple
intro such as Zytrax Tech Stuff - Regular Expressions - A Gentle User Guide and Tutorial.

BTW that’s a pointer to the exact section you need, but I recommend
you digest at least the first half of that guide - it’s not long or
difficult, and will serve you well in the future.

HTH,

You don’t need regular expressions, just use normal prefix
location:

location /my_ws {
    allow ...
    deny all;
}

See Module ngx_http_core_module for details.
