if ($$CGIObj->user_agent()=~m/Nav/i) {
print qq(Pragma: no-cache\n\n); #No cache for Netscape Navigator!
} else {
print qq(Cache-Control: no-cache\n\n); #No cache for Internet Explorer!
}
i.e. the author believed that Netscape wouldn't interpret 'Cache-Control: no-cache'.
The HTTP Spec says that the Cache-Control header was introduced in Version 1.1.
So when did Netscape start being HTTP Version 1.1 compliant, if ever?
