Consider this:
http://www.w3.org/TR/1998/REC-html4...rm-content-type
[multipart/form-data]
The content "multipart/form-data" follows the rules of all multipart
MIME data streams as outlined in [RFC2045]...
A "multipart/form-data" message contains a series of parts, each
representing a successful control. The parts are sent to the
processing agent in the same order the corresponding controls appear
in the document stream...
Each part is expected to contain:
1. a "Content-Disposition" header whose value is "form-data".
2. a name attribute specifying the control name of the
corresponding control...
Thus, for example, for a control named "mycontrol", the corresponding
part would be specified:
Content-Disposition: form-data; name="mycontrol"
As with all MIME transmissions, "CR LF" (i.e., `%0D%0A') is used to
separate lines of data.
Take a look here. The devil is in the details.
