http:server-maximum-body-size object[Generic Function]

The HTTP server maximum request body size, in bytes. If the server reads more bytes while reading a request body then the request is aborted and the connection closed. This provides the server with some protection against errant clients. The maximum request body size may be modified per request after reading the headers by the http:server-service-headers-function function.
