When using the expected-content mode on a site with a large number of headers (>8192 chars), the check returns a CRITICAL: 500 Header line too long error.

Hello :)

According to my research, the error message on the header limit is not generated in the Centreon plugin. To find out more, could you give us the output of your command with the --debug option set?
