Window Scaling, 2/3
More problems…
Broken websites: websites running old versions of firewalls in front of their web servers are broken when scaling factor > 2 is negotiated
A more thorough testing (of over 10 million websites) has revealed 2-4% websites impacted by this issue
Proxy problems:
Popular web proxy TCP splicing option (has been disabled by default since 2006) has problems understanding the scale factor.
