Summary

Microsoft Internet Information Services (IIS) version 5.0 adds many new Active Server Pages (ASP) capabilities. This article describes how to use the new <SCRIPT> tag syntax to include ASP code in another page.

WARNING: ANY USE BY YOU OF THE CODE PROVIDED IN THIS ARTICLE IS AT YOUR OWN RISK. Microsoft provides this code "as is" without warranty of any kind, either express or implied, including but not limited to the implied warranties of merchantability and/or fitness for a particular purpose.
Previous versions of IIS allowed an ASP page to include the contents of another file using code similar to the following:
<!--#include file="FILE1.INC"-->
<!--#include virtual="/folder/FILE2.INC"-->
IIS 5.0 has extended the server-side <SCRIPT> tag to include a new SRC attribute as an alternative method to include another page. The new syntax may then look similar to the following:
<SCRIPT LANGUAGE="VBSCRIPT" RUNAT="SERVER"
SRC="FILE.INC"></SCRIPT>
All code in the included page appears to the scripting engine as though it were between the <SCRIPT> and </SCRIPT> tags. Therefore, unlike the #include directive, your included page should consist of raw code only.
For example, consider the following #include statement:
<!--#include file="file.inc"-->
This statement would need to include a page similar to the following:
<%
  For X = 1 To 5
    Response.Write "<p>Howdy!</p>"
  Next
%>
Now consider the following <SCRIPT> statement:
<SCRIPT LANGUAGE="VBScript" RUNAT="SERVER"
SRC="file.inc"></SCRIPT>
This page would need to include a page similar to the following:
For X = 1 To 5
  Response.Write "<p>Howdy!</p>"
Next
The <SCRIPT> example is treated by ASP as though the parent page contains the following syntax:
<SCRIPT LANGUAGE="VBScript" RUNAT="SERVER" SRC="file.inc">
For X = 1 To 5
  Response.Write "<p>Howdy!</p>"
Next
</SCRIPT>
Note: No actual code should placed between the <SCRIPT> and </SCRIPT> tags in the parent page, as it will be ignored.
The SRC attribute can use either relative or virtual paths, as shown in the following table:

Path StyleExample Syntax
RelativeSRC="file.ext"
RelativeSRC="folder\file.ext"
VirtualSRC="\folder\file.ext"
VirtualSRC="/folder/file.ext"
The following ASP code demonstrates how to use the new <SCRIPT> syntax to mix server-side and client-side scripting.
  1. Save the following ASP page as "ScriptTest.asp" to a Web folder with Script Access enabled:
    <%@LANGUAGE="VBSCRIPT"%>
    <html>
    <head>
    <title>Enhanced SCRIPT Example</title>
    </head>
    <body>
    <h2 align="center">Enhanced SCRIPT Example</h2>
    
    <p align="center">
    <form method="GET" name="objForm"
    action="<%=Request.ServerVariables("URL")%>">
      <input type="text" name="Message">
      <input type="submit" value="Submit">
    </form>
    </p>
    
    <SCRIPT LANGUAGE="VBScript" RUNAT="SERVER"
    SRC="server.inc"></SCRIPT>
    
    <SCRIPT LANGUAGE="JavaScript">
    <!--#include file="client.inc"-->
    </SCRIPT>
    
    </body>
    </html>
  2. Save the following code as "Server.inc" to the same folder:
    Dim strMessage
    strMessage = Request.QueryString("Message")
    If strMessage <> "" Then
      Response.Write vbCrLf & "<script for=""window"" event=""onLoad"" language=""JavaScript"">"
      Response.Write vbCrLf & "objForm.Message.value = '" & strMessage & "';"
      Response.Write vbCrLf & "showMessage('" & strMessage & "');"
      Response.Write vbCrLf & "</script>"
    End If 
  3. Next, save the following code as "client.inc" to the same folder:
    function showMessage(strText) {
       alert(strText)
    }
Notes:
    • When you first browse "ScriptTest.asp," the form is displayed and the client-side function is not called.
    • When you submit text to the page, the server-side script outputs another client-side function that displays the submitted text in the form's input box and in a pop-up window.
