Option Name:log_mime_hdrs
Default Value:log_mime_hdrs off
Suggested Config:

	The Cache can record both the request and the response MIME
	headers for each HTTP transaction.  The headers are encoded
	safely and will appear as two bracketed fields at the end of
	the access log (for either the native or httpd-emulated log
	formats).  To enable this logging set log_mime_hdrs to 'on'.
