Since updating to 2.2 web.page.get returns nothing on failed page loads. Successful page loads work normally. I've duplicated the issue on 2 windows machines and a Linux machine. 2.0.9 agents still work as expected.

Example:
-bash-4.1# zabbix_agentd -t web.page.gethttp://www.faileddomain.org/
web.page.gethttp://www.faileddomain.org/ [t|]
