ServerIron HTTP content health check - position of the content expectet

Is it necessary to put the expectet content coming back from the web server in reply to a content based HTTP health check done by the ServerIron into the first packet? Or is it OK to have the expectet content in one of the following data packets?

It does not really matter. The expected content might be in the first reply packet but it is as well OK if it is part of one of the following data packets. I would suggest to put the content as close to the beginning of the reply as possible and I would suggest as well to keep the replies as small as possible to reduce the amount of data the ServerIron needs to parse to find the expected content. Less health check traffic and less work to parse the health chek replies implies less MP CPU utilisation which is good.

Is there a maximum length for the reply? What is the maximum amount of time the ServerIron is going to wait for the end of the reply?

There is not any maximum size - keep in mind that it is good to reduce the HC traffic to a minimum. It is as well required that the real server is able to deliver the content needed to the ServerIron during the configured health check interval. The ServerIron is going to start a new health check as soon as the next interval starts. A health check which is running at this time (still sending data from the real server to the ServerIron) is getting declared as not successful.
