You don t need --header  Content-Length   LENGTH     curl --request POST --data-binary   template entry xml   URL   Note that GET request does not support content body widely   Also remember that POST request have 2 different coding schema  This is first form        nc -l -p 6666       curl  --request POST --data-binary   README  http   localhost 6666  POST   HTTP 1 1 User-Agent  curl 7 21 0  x86 64-pc-linux-gnu  libcurl 7 21 0 OpenSSL 0 9 8o zlib 1 2 3 4 libidn 1 15 libssh2 1 2 6 Host  localhost 6666 Accept      Content-Length  9309 Content-Type  application x-www-form-urlencoded Expect  100-continue     - - mode  rst  coding  cp1251  fill-column  80 - -    rst2html py README README html    contents     You probably request  this    -F --form name content             HTTP  This lets curl emulate a filled-in form in               which a user has pressed the submit button  This               causes curl to POST data using the Content- Type               multipart form-data according to RFC2388  This               enables uploading of binary files etc  To force the                content  part to be a file  prefix the file name               with an   sign  To just get the content part from a               file  prefix the file name with the symbol  lt   The               difference between   and  lt  is then that   makes a               file get attached in the post as a file upload                while the  lt  makes a text field and just get the               contents for that text field from a file
