Users can customize the content of the HTTP header in the new version of the definition method, and can add, delete,

USR-DR404 will automatically add Content-Length).The setting commands include "AT + HTPMODE, AT + HTPSV, AT + HTPTP,
AT + HTPURL, AT + HTPHEAD". For specific command setting procedures, please refer to the “AT command” chapter.
