I have configured this according to “http://www.c-sharpcorner.com/UploadFile/Ihelpable/httpcompression05022006094806AM/httpcompression.aspx?ArticleID=b0c4a586-97b4-4fbd-a95a-8b1200f0e068”. I tested compression using “http://www.whatsmyip.org/http_compression/” before and after configuring and it shows to be working. My client is running Windows XP. The site comes up fine after compressing on Firefox and Chrome, but IE7 cannot display the site. Adding a single aspx page to the exception list allows IE7 to display that page. Any suggestions on getting the site to display in IE7?
