#include <lib/inc/drogon/HttpRequest.h> virtual void setPassThrough(bool flag)=0
Set the request object to the pass-through mode or not. It's not by default when a new request object is created. In pass-through mode, no addtional headers (including server, date, content-type and content-length, etc.) are added to the request. This mode is useful for some applications such as a proxy.
