That's not the kind of scenario I meant with "the general case" :-)

For situations like that, I expect us to have a log-tailer that
gives a top(1) like display of whatever we have selected.

I should add here I envision a generic set of arguments to logtailers
which the libvarnishapi should handle for programs:

	-i tag[,tag...] -- include these tags
	-x tag[,tag...] -- exclude these tags

		If no -i option is given a '-i all' is implict.

	-I regexp -- only data matching regexp
	-X regexp -- exclude data matching regexp

	-C match regexps case-insensitive

So for this case your you present, the command would be:

	varnish-top -i header -C -I user-agent

Never attribute to malice what can adequately be explained by incompetence.
