# [How to do a PUT request with curl?](http://stackoverflow.com/questions/13782198/how-to-do-a-put-request-with-curl)
# Unfortunately, the -T is no substitute for -X PUT if you want to specify parameters with -d or -F.
# -T sends the content of a file via PUT. To achieve the GET after a redirect, add the parameter --location
#
# -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 RFC 2388. 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 <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload,
# while the < makes a text field and just get the contents for that text field from a file.
#
# curl -X POST -F user_id=xxxxxxx -F session_id=xxxxxxx -F photo_id=xxxxxxx -F photo=@xxxxxxx.jpg http://api.pai.ai/photos/upload
