+---This method adds the specified header and its value to the current request. It works similarly as ngx.req.set_header, with the exception that when the header already exists, the specified value(s) will be appended instead of overriden.
+---
+---When the specified `header_name` is a builtin header (e.g. User-Agent), this method will override its values.
+---
+---The `header_value` argument can either be a string or a non-empty, array-like table. A nil or empty table value will cause this function to throw an error.
+---
+---This feature was first introduced in the v0.1.18 release.
