我有一段代码是防注入的。。
<%
dim qs,errc,iii
qs=request.servervariables("query_string")
dim nothis(18)
nothis(0)="net user"
nothis(1)="xp_cmdshell"
nothis(2)="/add"
nothis(3)="exec%20master.dbo.xp_cmdshell"
nothis(4)="net localgroup administrators"
nothis(5)="select"
nothis(6)="count"
nothis(7)="asc"
nothis(8)="char"
nothis(9)="mid"
nothis(10)="‘"
nothis(11)=":"
nothis(12)=""""
nothis(13)="insert"
nothis(14)="delete"
nothis(15)="drop"
nothis(16)="truncate"
nothis(17)="from"
nothis(18)="%"
errc=false
for iii= 0 to ubound(nothis)
if instr(qs,nothis(iii))<>0 then
errc=true
end if
next
if errc then
response.write "<script language=""javascript"">"
response.write "parent.alert(‘非法操作!您提交了错误的信息...‘);"
response.write "self.location.href=‘index.asp‘;"
response.write "</script>"
response.end
end if
%>


但不知道如何使用。。。。

请大家指教一下。。另外能有其它的代码吗？
