Why CURL library is always sending packets with do not fragment bit ON

Hi All,I am new with CURL library. Currently I am facing an issue because CURL is sending HTTP requests with do not fragment bit ON of IP layer. So when packet size is more than MTU then those packets are dropped by the routers. From packet dump it is clear that all the packets sent by CURL library have do not fragment bit ON.Why CURL is always sending HTTP requests with do not fragment bit ON?Is there any way to tell CURL to make do not fragment bit OFF?ThanksSubrata
