I think he's talking about some external tool, like nagiosgraph, which 
runs some code when some patterns are matched.
The problem is to figure out what kind of data you're receiving. As you 
cn only check output and perfdata, you have to find some regexp which 
matches your check_http but nothing else.
>From what I guess, he's referring about the default map file which comes 
with nagiosgraph:
http://nagiosgraph.cvs.sourceforge.net/nagiosgraph/nagiosgraph/map?revision=1.10&view=markup&pathrev=HEAD

  170 # Service type: unix-www
  171 #   ouput:HTTP OK HTTP/1.1 200 OK - 1456 bytes in 0.003 seconds
  172 /output:HTTP.*?(\d+) byte.*?([.0-9]+) sec/
  173 and push @s, [ http,
  174                [ bps, GAUGE, $1/$2 ] ];

Thus his question is more for nagiosgraph's support than here.
As you don't have "bytes" when you get a 302, it won't match.
Yes, this should be changed anyway do get values from perfdata and not 
from output.
Makes me wonder if there is an easy way to check the command name 
launched in a perfdata plugin... Would be much simpler.
