Odd Corruption

[Alex Smith <alex@xxxxxxxxxxxxx>]

Hi,

Having weird issues with squid (Squid Cache: Version 2.6.STABLE6). It 
seems to be randomly trashing css files, so websites are left rendered 
incorrectly on IE, but fine in FF.

It's not an issue of the css being broken, as when the timestamp on it 
is changed, and squid is forced to redownload it - it displays fine in IE.

Any suggestions? Quite lost here.

Thanks

Alex
