Is the problem state you want to have a user fill out a form, save the
data on the local disk, reboot the computer, come back the next day,
move to another part of the form, and repeat this process, and then
eventually combine all the saved files into one file and upload them as
one XML document?

At first I want to save the XML instances, which has been occured by
user's filling in forms, thus I must use only the method "put" with
action="file:C:/...". If I use the method "multipart-post", then I must
use action="http://...", which can not save any instance into some file.
In extension of my purpose IE should be able to send instances to
server, which will work with them.

If it works with "multipart-post" method, which you have described, then
it will be super.
