I just think Apache's mod_deflate has a weak point. When client doesn't declare it accept encoding, apache returns an uncompressed object, but for this object mod_deflate also returns a "Vary: Accept-Encoding" header. This make some browsers be confused. In fact my current IE6 sp2 can't download that object. How to resolve it? my current thought is to write an input filter for apache, when client doesn't accept encoding, redirect the request to pathA which is not mod_deflate enabled. otherwise redirect the request to pathB which is mod_deflate enabled. both pathA and pathB have the same contents (or pathA is a softlink to pathB). //joy --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
