Data is posted in a similar 23manner as --data does, except that newlines and carriage returns are 24preserved and conversions are never done. 25 26Like --data the default content-type sent to the server is 27application/x-www-form-urlencoded. If you want the data to be treated as 28arbitrary binary data by the server then set the content-type to octet-stream: 29-H "Content-Type: application/octet-stream". 30 31If this option is used several times, the ones following the first append 32data as described in --data. 33
