2057	$slice_range variable does not work in set directive.	ptcong@…		"Hello,

I want to set proxy_cache_key dynamically with $cache_key variable.
It works fine with another variables, but with $slice_range this config does not work and give incorrect range from upstream.

{{{
set $cache_key ""$another_var $blahblah $slice_range"";
if ($something) {
set $cache_key ""$cache_key new"";
}

slice                   1m;
proxy_set_header        Range $slice_range;
proxy_cache_key $cache_key;
}}}

$slice_range only works when it's placed directly to proxy_cache_key as this:

{{{
slice                   1m;
proxy_set_header        Range $slice_range;
proxy_cache_key $old_cache_key$slice_range;
}}}

Is this a bug ?
