hi. i have a trouble and question!
my current configuration in nginx is like ..
only "/blah/" url can access..

================================
server {
location / {
return 403;
}
location ^~ /blah/ {
proxy_pass http://127.0.0.1:8888;
}
}
================================

but now i have to access "/" location, too
how to block excluding specific url in nginx?

to conclude,
i want to access the only "/" and "/blah/" (for example, aaa.com and aaa.com/blah/~~)

can anyone help me?
