Summary: --form type= parameter isn't sent

Initial Comment:
Using version 7.16.4 of curl:

/var/tmp/curl-7.16.4/src/curl -F "order=@input.xml;type=application/xml" http://localhost/

produces the following in the logs on the localhost server:

SERVER_NAME: localhost
PATH_INFO: /
CONTENT_LENGTH: "1967"
HTTP_CONTENT_TYPE: multipart/form-data; boundary=----------------------------9ab4290e7a8a
HTTP_USER_AGENT: curl/7.16.4 (i686-pc-linux-gnu) libcurl/7.16.4 OpenSSL/0.9.7e zlib/1.2.2 libidn/0.5.8
SCRIPT_NAME: /
SERVER_PROTOCOL: HTTP/1.1
HTTP_HOST: localhost
REMOTE_ADDR: 10.0.0.10

REQUEST_URI: /
SERVER_PORT: "80"

Note the content-type begins with multipart/form-data. This should be application/xml as given by the type parameter to --form.

No, then you've misunderstood what type that sets.

The "type=" passed to --form sets the content-type for that specific
formpart in the post. If you want to change the Content-Type for the whole
post (which is the content-type you showed here) you need to use -H
"Content-Type: yadayada"

BUT, it is very unlikely that you want to change the primary Content-Type
if you do multipart formposts, and also if you do you'll make a broken post
since you can't possibly know what boundary string curl will use and that
needs to be included in that Content-Type: header for the formpost to
work.
