如何处理超时事件？
1、IIS为一个死循的执行过程设定执行时间（缺省为90秒）超时事件：
<%response.buffer=true%>
<body><html>
<%
DO
counter=counter+1
response.write counter & "<br>"
response.flush
LOOP
%>
</body></html>
2、自定义时间。用程序设定超时事件的时间段：
<%
response.buffer=true
server.scripttimeout=20
%>
<body><html>
<%
DO
counter=counter+1
response.write counter & "<br>"
response.flush
LOOP
%>
</body></html>
3、干涉超时时间段。捕获超时：
<%@ trANSACTION=Required%>
<%
response.buffer=true
server.scripttimeout=20
%>
<html><body>
</body>
<%
DO
counter=counter+1
response.write counter & "<br>"
LOOP
response.flush
response.write "脚本运行完啦!"
%>
</html>
<%
Sub OnTransactionAbort()
response.clear
Response.Write "噢,脚本运行超时了!"
end sub
%>
4、绕过超时事件：
<%@ trANSACTION=Required%>
<%
response.buffer=true
server.scripttimeout=40
%>
<html><body>
</body>
<%
DO UNTIL counter=400
counter=counter+1
response.write counter & "<br>"
LOOP
response.flush
response.write "脚本运行完啦!"
%>
</html>
<%
Sub OnTransactionAbort()
response.clear
Response.Write "噢,脚本运行超时了!"
end sub
%>
