注意要對(duì)所有的request對(duì)象進(jìn)行過(guò)濾：包括 request.cookie, request.ServerVariables 等等容易被忽視的對(duì)象：
復(fù)制代碼代碼如下:
function killn(byval s1) '過(guò)濾數(shù)值型參數(shù)
if not isnumeric(s1) then
killn=0
else
if s1<0 or s1>2147483647 then
killn=0
else
killn=clng(s1)
end if
end if
end function
function killc(byval s1) 過(guò)濾貨幣型參數(shù)
if not isnumeric(s1) then
killc=0
else
killc=formatnumber(s1,2,-1,0,0)
end if
end function
function killw(byval s1) '過(guò)濾字符型參數(shù)
if len(s1)=0 then
killw=""
else
killw=trim(replace(s1,"'",""))
end if
end function
function killbad(byval s1) 過(guò)濾所有危險(xiǎn)字符，包括跨站腳本
If len(s1) = 0 then
killbad=""
else
killbad = trim(replace(replace(replace(replace(replace(replace(replace(replace(s1,Chr(10), "<br>"), Chr(34), """), ">", ">"), "<", "<"), "&", "&"),chr(39),"'"),chr(32)," "),chr(13),""))
end if
end function
