Viewstate is just a hidden input field. Your client has to make sure to post
back all fields that contain data, including hiddens. So if the application
spits back a form like this:
<form action="foo.php" method="POST">
<input type="text" name="Name" value="" />
<input type="submit" name="Submit" value="Go" />
<input type="hidden" name="ImportantData" value="my important data
here" />
</form>
You need to post back:
"Name=Whatever Name They Typed&Submit=Go&ImportantData=my important data
here"
In the ASP.NET case, the Viewstate field is equivalent to ImportantData.
