Rails - Jul 2008 - Bizarre IE 7 error - res://ieframe.dll/dnserrordiagoff.htm

Hi all,

Ruby 1.8.6-p111
Rails 1.2.6
Windows XP Pro
IE 7

Posting this for posterity''s sake, and to see if anyone else hit this
issue.

I sporadically hit a strange error in IE7 when I hit a submit button
on a form within a Rails app.

res://ieframe.dll/dnserrordiagoff.htm

Further investigation revealed that, when I hit this error, it was
never reaching the controller, which I thought was odd. Also, I did
NOT see the same behavior in Firefox 2.x (it worked fine). The results
I found on Google for that error didn''t make much sense in the context
of a Rails app.

As best as I can figure it was the result of trying to pass too much
data over an http request (I tried both POST and GET). I noticed that
when I tried to pass smaller result sets via the form to a controller
it worked fine, but when the result set was very large it would choke
with this error (or redirect, or whatever you want to call it). The
solution, in my case, was to just pass the minimal information
necessary and do a second lookup in the controller.

I hope this helps some future googlers. If anyone else any insights on
this issue they''d like to share, please do.

Regards,

Dan

A colleague of mine pointed me to this article:

http://support.microsoft.com/kb/208427

In short, 2k limit for GET requests. I''m still not sure why
it''s
failing for a POST, though.
