Description
http://stackoverflow.com/questions/26976535/variable-interpolation-inside-map-directive
I am trying to map a variable inside the http directive in Nginx.
When left alone, the variable alone gets expanded, if I add anything else to the string the expansion stops working.
http {
map $host $foo {
#default "$host"; # - this works fine and returns 'localhost'
default "This is my host: $host"; # - THIS DOESN'T WORK
}
server {
location / {
echo $foo;
}
}
}

I would also like to base map conditions on existing variables...
map $host $public_domain {
default example.com;
}
map $http_referer $landing_request {
hostnames;
*.$public_domain 0; # THIS DOESNT WORK !!!
default 1;
}

It's not clear what you are trying to do with the example, as it's expected to always return 0 if the line in question will work. But anyway, there are no plans to support variables in source values.

Just updated the comment. It was meant to compare the $http_referer with $public_domain.
Cheers

Support of complex values in resulting strings is available in nginx 1.11.0.
This is expected behaviour. Only a single variable can be used as a resulting value, see http://nginx.org/r/map:
Support for combinations of multiple variables may be added in the future.
