-HttpGetRequestBody and HttpGetResponseBody.
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Make normalized body data available to the script through
-HttpGetRequestBody and HttpGetResponseBody.
-
-There no guarantees that all of the body will be available.
-
-Example:
-
-::
-
-  function log(args)
-      a, o, e = HttpGetResponseBody();
-      --print("offset " .. o .. " end " .. e)
-      for n, v in ipairs(a) do
-          print(v)
-      end
-  end
-
-HttpGetRequestHost
-~~~~~~~~~~~~~~~~~~
-
-Get the host from libhtp's htp_tx_request_hostname(tx), which can either be
-the host portion of the url or the host portion of the Host header.
-
-Example:
-
-::
-
-  http_host = HttpGetRequestHost()
-  if http_host == nil then
-      http_host = "<hostname unknown>"
-  end
-
-HttpGetRequestHeader
-~~~~~~~~~~~~~~~~~~~~
-
-::
-
-  http_ua = HttpGetRequestHeader("User-Agent")
-  if http_ua == nil then

-::
-
-  server = HttpGetResponseHeader("Server");

-  rl = HttpGetRequestLine();

-HttpGetRequestUriNormalized

-Flow variables
---------------
-
-It is possible to access, define and modify Flow variables from Lua. To do so,
-you must use the functions described in this section and declare the counter in
-init function:
-
-::
-
- function init(args)
-     local needs = {}
-     needs["tls"] tostring(true)
-     needs["flowint"] = {"tls-cnt"}
-     return needs
- end
-
-Here we define a `tls-cnt` Flowint that can now be used in output or in a
-signature via dedicated functions. The access to the Flow variable is done by
-index so in our case we need to use 0.
-
-::
-
- function match(args)
-     a = SCFlowintGet(0);
-     if a then
-         SCFlowintSet(0, a + 1)
-     else
-         SCFlowintSet(0, 1)
-     end
-
-SCFlowintGet
-~~~~~~~~~~~~
-
-Get the Flowint at index given by the parameter.
-
-SCFlowintSet
-~~~~~~~~~~~~
-
-Set the Flowint at index given by the first parameter. The second parameter is the value.
-
-SCFlowintIncr
-~~~~~~~~~~~~~
-
-Increment Flowint at index given by the first parameter.
-
-SCFlowintDecr
-~~~~~~~~~~~~~
-
-Decrement Flowint at index given by the first parameter.
