一段防注入的通用脚本

放在conn.asp里就行了。

屏蔽通过地址栏攻击

url=Request.ServerVariables("QUERY_STRING")

if instr(url,";")>=1 then

url=Replace(url,";","；") : Response.Redirect("?" & url)

end if

屏蔽通过表单攻击

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 ("对不起,请不要输入非法字符!")

response.end

end if

next
