Check_http bug ?

Hi All,

I have for a number of days now, being trying to figure out why the
Check_http tool will not successfully against a site of mine.

I do not get any error message, but I also do not get a success message.
The reason seems to be due to a malformed HTTP GET request that the tool
is making. The HTTP spec specifies that the header should end in a double
carriage return, and if any more data is being sent a content-length must
be specified.

I am using “check_http (netsaint-plugins 1.2.9-4) 1.32.2.6”

As you can see from the tcpdump output in the last packet there are three
sets of carriage return line feeds, one more than should be sent.
