Page aspx not displayed with ie7

[Ide]

Hi

I have a bug with some links on my website reposting the same aspx page with
some filters:
The filtered page is
--> correctly displayed using localhost with ie7
--> correctly displayed using a dev server with firefox
--> but not displayed using the same server with ie7 : in this case I have
used Fiddler to try and check what's going on and see that the HTML content
of this page that
should be displayed is indeed transmitted and shown in Fiddler but is not
displayed in ie7

How can this be??
