KeepAlive
KeepAlive number
Default number: 5
Server config
Chances are that if a user logs on to your site, he will reaccess it
fairly soon. To avoid unnecessary delay, this command keeps the
connection open, but only for number
requests, so that one user does not hog the server. You might want to
increase this from 5 if you have a deep directory structure. Netscape
Navigator 2 has a bug that fouls up keepalives. Apache v1.2 and
higher can detect the use of this browser by looking for
Mozilla/2 in the headers returned by Netscape. If
the BrowserMatch directive is set (see Chapter 13), the problem disappears.
