There's been at least one other inquiry about using variables in proxy
directives on the IRC channel:
how can I obtain a proxy pass rule like the following:
proxy_pass http://localhost:7777/vhost/http/$host/;
unfortunately $host is not substituted do I need to use rewrite rules
first?
I think this is a reasonable request... would it be difficult to
implement?

Hello,
I'm now trying to use variables to allow me to re-use configuration
files easily. The basic idea is:
upstream some-mongrel-cluster {
...
}
server {
...
set $rails_proxy http://some-mongrel-cluster;
include macros/rails.conf;
}
Then, rails.conf has the standard rails stuff and this line:
proxy_pass $rails_proxy;
Not surprisingly, this doesn't work. :) I am wondering what I might do
to make it work, but I need to know:
- Whether the problem is that the variable is not available from
mod_http_proxy (since "set" is a mod_rewrite command?) or just that
proxy_pass does not support using variables
- If proxy_pass does not support variables, how do I make it do this?
Where in the source is a good place to see how variables work?
