  对于一个表单，使用PUT和GET方法
  这同样适用于从带有查询字符串连接而来的页面，比如?ID=236454
  < %
  If Request.Querystring = "" Then
  Response.Write("< p align=""center"" >< font face=""Arial"" >There Was An
  Error.< br >" & vbCrLf)
  Response.Write("No Data Was Posted.< /font >
  " & vbCrLf)
  Response.End
  End If
  % >
  为了含概上面例子中的情况，要做下面的工作。尽管还有简单的方法，但是这个例子对于初学者，将是很好的学习基本原理的方法。
  < %
  IsData = 0
  If Request.Form < > "" Then IsData = IsData + 1
  If Request.Querystring < > "" Then IsData = IsData + 1
  
  If IsData = 0 Then
  Response.Write("< p align=""center"" >< font face=""Arial"" >There Was An Error.< br >" & vbCrLf)
  Response.Write("No Data Was Posted.< /font >
  " & vbCrLf)
  Response.End
  End If
  % >
  或者
  < %
  IsData = "No"
  If Request.Form < > "" Then IsData = "Yes"
  If Request.Querystring < > "" Then IsData = "Yes"
  
  If IsData = "No" Then
  Response.Write("< p align=""center"" >< font face=""Arial"" >There Was An Error.< br >" & vbCrLf)
  Response.Write("No Data Was Posted.< /font >
  " & vbCrLf)
  Response.End
  End If
  %>
