local ngx_resp = require "ngx.resp"

Description
This Lua module provides Lua API which could be used to handle HTTP response.
Methods
All the methods of this module are static (or module-level). That is, you do not need an object (or instance) to call these methods.
add_header
syntax: ngx_resp.add_header(header_name, header_value)
This function adds specified header with corresponding value to the response of
current request. The header_value
could be either a string or a table.
The ngx.resp.add_header
works mostly like:
- ngx.header.HEADER
- Nginx's add_header directive.
However, unlike ngx.header.HEADER
, this method appends new header to the old
one instead of overriding it.
Unlike add_header
directive, this method will override the builtin header
instead of appending it.
