If you want to set a cookie (i.e., adding Set-Cookie response headers
on the HTTP protocol level), then assigning to the Nginx variable
$cookie_XXX will not do what you want. (This has nothing to do with
Lua and this is how the Nginx core works right now.)

To achieve that, you need to add the Set-Cookie response headers
explicitly. For example, in Lua you can do something like this:

ngx.header['Set-Cookie'] = {'a=32; path=/', 'b=4; path=/'}

will yield the HTTP response headers

Set-Cookie: a=32; path=/
Set-Cookie: b=4; path=/
