I have done quite a bit of this __VIEWSTATE crap, and in this case,
you're going to have to do a bit more than just simply automating this
... It appears that these folks really don't want you to do what
you're attempting to do.
You see if you would have examined the page source a little more
closely, you would have seen the two hidden Iframes, which are PHP
pages ! I have stripped down this page quite a bit, please see the
attached html file, which does successfully log me in, and it also
shows you what the page has been hiding, however it does not automate
anything and thus, is not what you want, but should give you a better
idea of what you're up against. Thanks.
