Some questions about using include in ASP

include| question one. Benefits of using include:
Make the program modular, easy to maintain, and improve the reusability, reduce the probability of error occurrence, shorten the development cycle.
Two. Use include format:
1. Relative path <!--#include file= "common.asp"--> default to the common.asp in the directory where the ASP is calling it
<!--#include file= ". /common.asp "--> The directory of the ASP where it was called common.asp
2. Absolute path
<!--#include virtual= "common.asp"--> defaults to common.asp under the root directory
<!--#include virtual= "test/common.asp" under the--> root directory under the test directory common.asp

Common.asp
function AddOne (i)
Addone=i+1
End Function
Sample.asp
<! --#include virtual= "test/common.asp"-->
<% Dim i I=1 i=addone (i)
Response.Write "U Got" &i& "points"
%>
Three. Several main points:
1. Cannot cycle call if there are a.inc and b.inc if B.inc #include a.inc then a.inc cannot #include b.inc
2. It is recommended that you do not use the default. inc suffix to use. asp, so as not to be downloaded directly by others, causing harm. 3. #include优先于asp解析, so the following procedure is wrong sample1.asp
<%
Dim i I=1 i=addone (i)
Response.Write "U Got" &i& "points"
Dim Incneed incneed=1.asp
%>
<!--#include virtual= "test/<%=incneed%>" "-->
If you use Select Case, both 1.asp and 2.asp are loaded ahead of time, but when calling a function, it seems to recognize only the last include, whether incneed=1 or 2, the answer is U got 3 points
