Looks like the recent Microsoft patch (MS06-042) , which is a cumulative Security Update for Internet Explorer is affecting some IE 6.0 SP1 users. So, if you are a IE 6.0 SP1 user, you may be affected by this issue when "visiting a website that use HTTP 1.1 and compression"
MS updated the advisory to contain this information and plan to re-release the patch by August 22, for those users only.

You may ask how many users can be affected by this. I really dont know, but I suspect that the number is not high (but I can be completely wrong). The reason is that HTTP 1.1 compression is not (or at least wasn't ) enable by default on both IIS and Apache web servers, the most used webservers.

If you are one of those users, please let me know if you are seeing this issues.
