The check_http plugin doesn't care what web server is vending the
page... It could be a perl script cat'ing a file to port 80 for all it
cares. If a page is vended by the web server, doesn't that directly
imply that the web server is up and functional? What other test are you
interested in? If you're concerned that the page is vended fully,
consider adding the '-s' option to your command definition like '-s
\/html'. Then it will only be OK if it sees '/html' in the stream.
