I can't really test this easily so I am asking instead. I have this location statement in my nginx.conf:

location ~* ^/(api/abcd)/ {
...
}

Now I want to match against "api/efgh". Then the regex should be something like this?

location ~* ^/(api/(abcd|efgh))/ {
...
}

OR

location ~* ^/api/(abcd|efgh)/ {
...
}

OR

something else?
