nokeepalive
This
disables KeepAlive
(see Chapter 3).
Some versions of Netscape claimed to support
KeepAlive, but they actually had a bug that meant
the server appeared to hang (in fact, Netscape was attempting to
reuse the existing connection, even though the server had closed it).
The directive:
BrowserMatch "Mozilla/2" nokeepalive
disables KeepAlive for those buggy
versions.[10]
[10] And, incidentally, for early versions of Microsoft Internet Explorer, which unwisely pretended to be Netscape Navigator.
