The main problem is not old browsers. They do not send "Accept-Encoding: gzip" header so they do not receive compressed content. I know two browsers that send "Accept-Encoding" and can incorrectly handle compressed response - MSIE 4.x and Mozilla 0.9.1. The main problem is proxies, especially Squid (~70% of all proxies) Proxies can store compressed response and return it to browser that does not understand gzipped content. So you should by default disable encoding for requests with "Via" header and HTTP/1.0 requests (HTTP/1.1-compatible proxy must set "Via" header, HTTP/1.0-compatible should but not have). Igor Sysoev
