IE empty params

Rails
1

Hi,

Im getting a strange problem. I have a rails application (running rails
3.0.0), which uses NTLM to deal with the auth. The problem is that, with
IE (all versions) when we use POST as a result of a form, the “params”
variable is always empty, and so the application crashes. The strangest
thing is that it works with both Firefox and Chrome, and in IE when I
TURN OFF the NTLM. Also there is another application running on the same
server, that uses IE and NTLM, with basiclly the same configurations (i
guess) and runs OK. The only difference is that it runs on rails 2.2.2.

Has anyone got any ideia why this is happening ?

Thank a lot!

Have you checked that the html of the page is valid by copying the
complete page html (View > Page Source or similar in your browser) and
pasting it into the w3c html validator site? Differing operation
between browsers is often the result of invalid html.

Did you copy/paste the complete source of the page?

Are you using javascript? If so try with firebug in firefox and see
if it gives any errors.

Could it be a Rails 3.0.0 issue? Perhaps an upgrade to 3.0.3 would be
advisable.

understand why it works when i take the NTLM auth method out of the
picture…

If you look at the app log and compare it between FF and IE what
differences do you see?

You could post the relevant bits of log if appropriate.

Could it be this?

It is ancient and I can’t say I understand it, but the log looks very
like yours.

Otherwise I have reached the end of my knowledge span I think.

Thks for ur concern Colin. I even created a simple-mini app just using
the standard Rails Scaffold, in order to isolate the problem. And it
still remains. The main difference is that, in FF it passes (besides the
necessary parameteres) the “authenticity_token” and the “commit”.

PS: I had to turn off protect_from_forgery in the
application_controller.rb in order to get it working in IE. Or else i’d
get a “invalid authenticity token”.
