<div>It seems like the set command was designed for use in a narrow set of circumstances. But I think it would be a lot more useful if the variables it defines could be used globally with any directive.</div><div><br></div>
I am trying to use the 'set' command in order to define my own variables that define things that may vary by server in a main nginx.conf file so that a generic reusable include file can later use those variables. It seems that the variables only work in certain places with certain directives.<div>
<br></div><div>Is there a reason I can't use variables set this way more widely? I would like to be able to use variables like this anywhere in the config files.</div><div><br></div><div><div>In the example below, I define two variables with the 'set' command, $rootfolder and $backend.</div>
<div><br></div><div>The $rootfolder variable doesn't work with the include directive and the $backend doesn't work with the proxy_pass directive.</div><div>But the $rootfolder does work with the $alias directive.</div>
