Aaron Cannon nobody The GZip middleware currently only tests if the browser is IE. However, there are only three browser versions that I was able to identify with bugs in how they handle GZipped content. They are IE5, IE6 and Netscape4. However, the current code assumes that all IE versions have such bugs, and doesn't test at all for Netscape. This means that a lot of pages that could be compressed aren't being compressed because the browser is IE. Furthermore, the broken versions of IE and Netscape came out over 10 years ago, so they are a small minority. Bug closed HTTP handling dev Normal fixed gzip middleware Ready for checkin 1 0 0 0 0 0
