Use a L6 sample fetch on an HTX streams or a HTX health-check is meaningless because data are not raw but structured. So now, these sample fetches fail when called from an HTTP proxy. In addition, a warning has been added in the configuration manual, at the begining of the L6 sample fetches section. Note that req.len and res.len samples return the HTX data size instead of failing. It is not accurate because it does not reflect the buffer size nor the raw data length. But we keep it for backward compatibility purpose. However it remains a bit strange to use it on an HTTP proxy. This patch may be backported to all versions supporting the HTX, i.e as far as 2.0. But the part about the health-checks is only valid for the 2.2 and upper.
