をまず見てね！

と言う訳で先人の知恵を借りて、文字列で処理をする事に。差分のみ

---------------------------------------------
-- http request
---------------------------------------------
function httpRequest( request )
  local len = #request
  if len < 4 then return 0 end

  local result = 0
  if request[len - 3] == 0x0D and
     request[len - 2] == 0x0A and 
     request[len - 1] == 0x0D and 
     request[len - 0] == 0x0A then
    Logput( 1, 'end of the request message.' )


    local reqStr = CharFromTbl( request )
    local lineTbl = strSplit( reqStr, "\r\n" )
    local line1Tbl = strSplit( lineTbl[1], " " )

    local methodStr = line1Tbl[1]
    local urlStr = line1Tbl[2]
    local httpVersionStr = line1Tbl[3]

    if strCmp( methodStr, 'GET' ) == 0 then
      local fileData = methodGet( urlStr, httpVersionStr )
      if fileData ~= nil then 
        index200( fileData )
        result = 200
      else
        index404()
        result = 404
      end
    elseif strCmp( methodStr, 'PUT' ) == 0 then
      index405()
      result = 405
    elseif strCmp( methodStr, 'POST' ) == 0 then
      index405()
      result = 405
    elseif strCmp( methodStr, 'DELETE' ) == 0 then
      index405()
      result = 405
    else
      index400()
      result = 400
    end

  end

  return result
end


---------------------------------------------
-- method get
---------------------------------------------
function methodGet( urlStr, verStr )
  local file = {}
  local methodTbl = 
  {
    { url = "/",           path = "D:\\temp\\index.html" },
    { url = "/index.html", path = "D:\\temp\\index.html" },
    { url = "/index.htm",  path = "D:\\temp\\index.html" },
  }


  for i = 1, #methodTbl do
    if strCmp( urlStr, methodTbl[i].url ) == 0 then
      file = FileRead( methodTbl[i].path )
      return file
    end
  end


  return nil
end


---------------------------------------------
-- divide string by ts and enter table.

---------------------------------------------
function strSplit(str, ts)
  -- 引数がないときは空tableを返す
  if ts == nil then return {} end

  local t = {} ; 
  i=1
  for s in string.gmatch(str, "([^"..ts.."]+)") do
    t[i] = s
    i = i + 1
  end

  return t
end

※ ともすれば変数がテーブルなのか？文字列なのか？それとも他の型なのか判らなくなってくるので、変数名、、、。
