`set_by_lua_block` nginx-lua module directive that sets specified variable with a result from Lua code	`return os.time()` sample Lua code that returns current unix timestamp
`$test` this variable will contain value returned by Lua code	`return 200 $test;` here we just send `$test` variable value to client
