1. why is it named "content" and not aligned the the request body variable RequestBodyLength? Should we create an alias? 2. when is it populated? Looks like it is populated only when no response body processor is active. Is it correct? Is it aligned with ResponseBody? 3. Does forceResponseBodyVariable have some implications on ResponseContentLength? From https://github.com/corazawaf/coraza/pull/1565.
From #1565.
