问一下，在session_onend事件中，session("id")这类的值还存不存在？

Question

if( Session["id"] == null )

Answer 1

dim id,fl
id=session("id")
fl=session("fl_sf")
application.Lock
if fl="1" or fl="2" then
dim i,newstr,xx

newstr=""
if fl="1" then
xx=split(application("online_user_danwei"),"#")
elseif session("fl_sf")="2" then
xx=split(application("online_user_geren"),"#")
end if
num=ubound(xx)
for i=0 to num if cstr(id)<>cstr(trim(xx(i))) then
newstr=newstr&xx(i)
if i<>num and num<>1 then
newstr=newstr&"#"
end if
end if
next
if fl="1" then
application("online_user_danwei")=newstr
elseif fl="2" then
application("online_user_geren")=newstr
end if
end ifif( Session["id"] == null ) 她是不应该执行for的！！
