class Bauxite::Action
	# Replays the current GET request and asserts that the HTTP headers
	# returned by that request match each of the +args+ specified.
	#
	# Note that this action results in an additional HTTP GET request to
	# the current browser url.
	#
	# The syntax of +args+ is:
	#     "header_name1=expression1" "header_name2=expression2" ...
	#
	# Where +expression+ is a regular expression. Note that multiple
	# headers can be asserted in a single #asserth call. Also note that
	# if the same header is specified more than once, the value of the
	# header must match every expression specified.
	#
	# For example:
	#     # assuming response headers { 'Content-Type' => 'text/plain' }
	#     asserth "content-type=plain"
	#     asserth "content-type=^text" "content-type=/plain$"
	#     # => these assertions would pass
	#
