	# ssi_with_retries - Does the server side include of a resource.
	# if the ssi call returns an error we'll retry it up to
	# the number of times requested by the caller.
	# If we still have a proble, no text is appended to the
	# output and we set some global variables.
	# to indicate to the caller an SSI error occurred.
	# All of this is supposed to deal with the issues described
	# in LonCAPA BZ 5631 see:
	# http://bugs.lon-capa.org/show_bug.cgi?id=5631
	# by informing the user that this happened.
	#
	# Parameters:
	# resource - The resource to include. This is passed directly, without
	# interpretation to lonnet::ssi.
	# form - The form hash parameters that guide the interpretation of the resource
	#
	# retries - Number of retries allowed before giving up completely.
	# Returns:
	# On success, returns the rendered resource identified by the resource parameter.
	# Side Effects:
	# The following global variables can be set:
	# ssi_error - If an unrecoverable error occurred this becomes true.
	# It is up to the caller to initialize this to false
	# if desired.
	# ssi_last_error_resource - If an unrecoverable error occurred, this is the value
	# of the resource that could not be rendered by the ssi
	# call.
	# ssi_last_error - The error string fetched from the ssi response
	# in the event of an error.
