it works now. I did not change nothing in varnish, I changed PHP code.

This was original code:
if(isset($_SERVER["HTTP_USER_AGENT"]) and strpos($_SERVER["HTTP_USER_AGENT"], 'MSIE')) {
   ini_set('zlib.output_compression', 'Off');
}

I replaced it with:
ini_set('zlib.output_compression', 'Off');

Now it works OK. Just to let you know, I am not sure, if it is bug,
or...
