you could take the logon credentials and if correct set an encrypted
cookie on the users machine (over SSL) plus pass something to the
serverB that should handle the users upload, then passback the action
of the form to point to the serverB, then server B will use the info
given to it to authenticate the user based on that cookie and allow
the upload.
