My website is an ASP.net web application hosted on a Windows server. I have employed gzip content compression on this site, which reduces the pages' sizes by more than 70% in most cases. Gzip compression is widely used and supported by millions of websites. However, when gzip compression is turned on for my site, your website evaluation service fails - it can't find meta tags, it can't read any HTML text, it is basically worthless. My website grade falls to a 16 with gzip enabled, when I can actually get a 60 or 70 score with gzip compression turned off. I think your website, as awesome and handy as it is, should support this very basic compression standard which is supported by 99.9% of the browsers, webservers and websites out there.
