# Server push is a Netscape 3+ hack incompatible with MSIE, Lynx, and others.
# Even Communicator 4.51 has bugs with it, especially during page reload.
# http://www.browsercaps.org used as source of compatible browsers.
+# Safari (WebKit) does not support it, despite a UA that says otherwise (bug 188712)
+# MSIE 5+ supports it on Mac (but not on Windows) (bug 190370)
