Viewstate error with Macintosh browsers... a clue.

[Max Metral]

I get sporadic viewstate errors from Macintosh browsers. I get mailed the
form values when this happens, and it appears that the problem is the
encoding of the POST value from the browser. Something like:

__EVENTTARGET=& __EVENTARGUMENT =&__VIEWSTATE=d DwxOTk2NDc2Nzk0 OztsPFQ<more
stuff cut out>hM%3d&T%3aH %3aR%3aAToken=& T%3aH....

As you may see, the arguments after viewstate are just a mess. The browser
seems to be escaping stuff it just shouldn't be. Given that I can't change
the browser, any suggested workarounds?

Hi Max,

From your description, you'll sometimes recieve VIEWSTATE errors ( is it
"Viewstate is invalid"? ) when try visiting asp.net web pages from your mac
browser, yes?

Based on my research, such problem is likely due to the client browser
rathenr than the serverside application . What's the browser are you using
when suffering the problem? IE or netscape or some other ones . There're
some existing issues on some Macintosh browsers which can't send VIEWSTATE
correct ly such as
"Viewstate is Invalid on Macintosh Safari Browser"

If you found that the problem only occur when visiting via that particular
browser, I think the problem must be something wrong with that browser.

Thanks.

We are also experiencing "Invalid_Viewst ate" errors that all seem to be
coming from Safari browsers. Has Microsoft confirmed this? This seems to be
the only reference I have found to this particular issue. We use the
viewstate fairly extensively in our application, do we need to warn Safari
users? Is there a work-around?
