一段asp防注入的泛型指令碼

放在conn.asp裡就行了。

'屏蔽通過地址欄攻擊
url=Request.ServerVariables("QUERY_STRING")
if instr(url,";")>=1 then
url=Replace(url,";","；") : Response.Redirect("?" & url)
end if
'屏蔽通過表單攻擊
for each item in request.form
stritem=lcase(server.HTMLEncode(Request.form(item)))
if instr(stritem,"select ")>=1 or instr(stritem,"insert ")>=1 or instr(stritem,"update ")>=1 or instr(stritem,"delete ")>=1 or instr(stritem,"exec ")>=1 or instr(stritem,"declare ")>=1 then
response.write ("對不起,請不要輸入非法字元!")
response.end
end if
next
