以下为引用的内容：

<%
Dim Fy_Url,Fy_a,Fy_x,Fy_Cs(),Fy_Cl,Fy_Ts,Fy_Zx
'---定义部份头------
Fy_Cl = 1 '处理方式：1=提示信息,2=转向页面,3=先提示再转向
Fy_Zx = "index.Asp" '出错时转向的页面
'---定义部份尾------

On Error Resume Next
Fy_Url=Request.ServerVariables("QUERY_STRING")
Fy_a=split(Fy_Url,"&")
redim Fy_Cs(ubound(Fy_a))
On Error Resume Next
for Fy_x=0 to ubound(Fy_a)
Fy_Cs(Fy_x) = left(Fy_a(Fy_x),instr(Fy_a(Fy_x),"=")-1)
Next
For Fy_x=0 to ubound(Fy_Cs)
If Fy_Cs(Fy_x)<>"" Then
If Instr(LCase(Request(Fy_Cs(Fy_x))),"'")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),"select")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),"update")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),"chr")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),"delete%20from")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),";")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),"insert")<>0 or Instr(LCase(Request(Fy_Cs(Fy_x))),"mid")<>0 Or Instr(LCase(Request(Fy_Cs(Fy_x))),"master.")<>0 Then
Select Case Fy_Cl
Case "1"
Response.Write "<Script Language=JavaScript>alert(' 出现错误！参数 "&Fy_Cs(Fy_x)&" 的值中包含非法字符串！\n\n 请不要在参数中出现：and,select,update,insert,delete,chr 等非法字符！\n\n我已经设置了不能SQL注入，请不要对我进行非法手段！');window.close();</Script>"
Case "2"
Response.Write "<Script Language=JavaScript>location.href='"&Fy_Zx&"'</Script>"
Case "3"
Response.Write "<Script Language=JavaScript>alert(' 出现错误！参数 "&Fy_Cs(Fy_x)&"的值中包含非法字符串！\n\n 请不要在参数中出现：,and,select,update,insert,delete,chr 等非法字符！\n\n设计了门，非法侵入请离开，谢谢！');location.href='"&Fy_Zx&"';</Script>"
End Select
Response.End
End If
End If
Next
%>

以上代码为较多网友所用，从使用的感言来看，效果显著。

以下为引用的内容：
Dim Query_Badword,Form_Badword,Err_Message,Err_Web,form_name

'------定义部份头----------------------------------------------------------------------

Err_Message = 1 '处理方式：1=提示信息,2=转向页面,3=先提示再转向
Err_Web = "Err.Asp" '出错时转向的页面
Query_Badword="'‖and‖select‖update‖chr‖delete‖%20from‖;‖insert‖mid‖master.‖set‖chr(37)‖="
'在这部份定义get非法参数,使用"‖"号间隔
Form_Badword="'‖%‖&‖*‖#‖@‖=‖select‖and‖set‖delete" '在这部份定义post非法参数,使用"‖"号间隔

'------定义部份尾-----------------------------------------------------------------------
'
On Error Resume Next
'----- 对 get query 值的过滤.
if request.QueryString<>"" then
Chk_badword=split(Query_Badword,"‖")
FOR EACH Query_form_name IN Request.QueryString
for i=0 to ubound(Chk_badword)
If Instr(LCase(request.QueryString(Query_form_name)),Chk_badword(i))<>0 Then
Select Case Err_Message
Case "1"
Response.Write "<Script Language=JavaScript>alert('传参错误！参数 "&form_name&" 的值中包含非法字符串！\n\n请不要在参数中出现：and update delete ; insert mid master 等非法字符！');window.close();</Script>"
Case "2"
Response.Write "<Script Language=JavaScript>location.href='"&Err_Web&"'</Script>"
Case "3"
Response.Write "<Script Language=JavaScript>alert('传参错误！参数 "&form_name&"的值中包含非法字符串！\n\n请不要在参数中出现：and update delete ; insert mid master 等非法字符！');location.href='"&Err_Web&"';</Script>"
End Select
Response.End
End If
NEXT
NEXT
End if

'-----对 post 表单值的过滤.
if request.form<>"" then
Chk_badword=split(Form_Badword,"‖")
FOR EACH form_name IN Request.Form
for i=0 to ubound(Chk_badword)
If Instr(LCase(request.form(form_name)),Chk_badword(i))<>0 Then
Select Case Err_Message
Case "1"
Response.Write "<Script Language=JavaScript>alert('出错了！表单 "&form_name&" 的值中包含非法字符串！\n\n请不要在表单中出现： % & * # ( ) 等非法字符！');window.close();</Script>"
Case "2"
Response.Write "<Script Language=JavaScript>location.href='"&Err_Web&"'</Script>"
Case "3"
Response.Write "<Script Language=JavaScript>alert('出错了！参数 "&form_name&"的值中包含非法字符串！\n\n请不要在表单中出现： % & * # ( ) 等非法字符！');location.href='"&Err_Web&"';</Script>"
End Select
Response.End
End If
NEXT
NEXT
end if

以上是另一种版本。

以下为引用的内容：
<%
Dim GetFlag Rem(提交方式)
Dim ErrorSql Rem(非法字符)
Dim RequestKey Rem(提交数据)
Dim ForI Rem(循环标记)
ErrorSql = "'~;~and~(~)~exec~update~count~*~%~chr~mid~master~truncate~char~declare" Rem(每个敏感字符或者词语请使用半角 "~" 格开)
ErrorSql = split(ErrorSql,"~")
If Request.ServerVariables("REQUEST_METHOD")="GET" Then
GetFlag=True
Else
GetFlag=False
End If
If GetFlag Then
For Each RequestKey In Request.QueryString
For ForI=0 To Ubound(ErrorSql)
If Instr(LCase(Request.QueryString(RequestKey)),ErrorSql(ForI))<>0 Then
response.write "<script>alert(""警告:\n请不要做任何尝试"");location.href=""index.asp"";</script>"
Response.End
End If
Next
Next
Else
For Each RequestKey In Request.Form
For ForI=0 To Ubound(ErrorSql)
If Instr(LCase(Request.Form(RequestKey)),ErrorSql(ForI))<>0 Then
response.write "<script>alert(""警告:\n请不要做任何尝试"");location.href=""index.asp"";</script>"
Response.End
End If
Next
Next
End If

将上述代码放入conn文件中即可，功能较全面……
