[mod_python] POSTed form fields?

The request object does not contain parsed (or even unparsed) POSTed
fields, so you need to read and parse them yourself:

(1) get the total length of the POSTed data from the "Content-length"
    header (available through the "headers_in" table in the request
    object);

(2) read the data in using the "read" method on the req object; NB:
    in mod_python 2.4.1, "read" can return a shorter data chunk than
    requested ("short read"); a patch had been submitted which
    rectifies the problem; alternatively you can do multiple "read"s
    until you get the whole length of your data;

(3) then you can parse the contents splitting it into key=value
    pairs separated by "&"s. There are some subtleties like multiple
    fields with the same name, file submission by POST,etc, to take
    care about.

Hope it will help,
