[Seaside] Strange problem with IE7

[Marco D'Ambros]

Hi,

I have a web site created with Seaside which works without any problem  
with Firefox, Safari and Opera.
However, when trying with Internet Explorer 7 I cannot even open the  
page, and I get on IE the following error message: "Impossible to open  
the site. Site not available or not found. Try again later".

The site is the following: http://churrasco.inf.unisi.ch/

Did that ever happen to some of you?

Cheers
Marco
