受<! #include file="filename.asp" --> 宏限制必须存在该文件并且会预先编译（不管前面是否加以条件）
经常有这样的要求，根据不同的需求要求include不同的文件如各个人的不同设置，所以要求能动态include文件。
代码如下：
<% Function include(filename) Dim re,content,fso,f,aspStart,aspEnd set fso=CreateObject("Scripting.FileSystemObject") set f=fso.OpenTextFile(server.mappath(filename)) content=f.ReadAll f.close set f=nothing set fso=nothing set re=new RegExp re.pattern="^\s*=" aspEnd=1 aspStart=inStr(aspEnd,content,"<%")+2 do while aspStart>aspEnd+1 Response.write Mid(content,aspEnd,aspStart-aspEnd-2) aspEnd=inStr(aspStart,content,"%\>")+2 Execute(re.replace(Mid(content,aspStart,aspEnd-aspStart-2),"Response.Write ")) aspStart=inStr(aspEnd,content,"<%")+2 loop Response.write Mid(content,aspEnd) set re=nothing End Function %>
使用范例：include("youinc.asp")
