Parse multipart input.
Arguments: fp : input file pdict: dictionary containing other parameters of conten-type header
Returns a dictionary just like parse_qs(): keys are the field names, each value is a list of values for that field. This is easy to use but not much good if you are expecting megabytes to be uploaded -- in that case, use the FieldStorage class instead which is much more flexible. Note that content-type is the raw, unparsed contents of the content-type header.
