Well,

There is no problem to let apache do its response with Vary header. It was 
strange to me apache has two versions of the same object in the cache. As 
explained earlier this might happen because MSIE introduces a white-space 
after comma in the Accept-Encoding header. (maybe an apache parse mistake).

Best Regards,
Fernando
