To my understanding (and anyone who can correct me if I am wrong, please do),
some versions of Microsoft Internet Explorer (MSIE) have problems with using the
HTTP/1.1 protocol with SSL. What this command does is to turn off keepalive
facility and force HTTP/1.0 responses (rather than HTTP/1.1 responses) when the
browser (User-Agent) is a version of MSIE. If you would like more information on
this, you might try the following page from the mod_ssl FAQ:
http://www.modssl.org/docs/2.8/ssl_faq.html#ToC49
Hope this helps.
