Events with ASP Page Do Not Work Correctly (266230)

SYMPTOMS

An "ad" insertion with event tags in an .asx file does not work as expected when it points to an ASP page that generates pages dynamically. Although the ASP page generates a different .asx file every time, Windows Media Player always uses the first one.

The following sample files demonstrate this behavior.

Sample .asx file:

<ASX version = "3.0">
  <title>Live Stream</title>
  <entry>
    <ref href = "mms://server1/station1"/>
  </entry>
  <EVENT NAME="ad" WHENDONE="RESUME">
	<ENTRYREF HREF="http://server1/dynasx.asp"/>
  </EVENT>
</ASX>
				

Sample ASP page:

<% @LANGUAGE="VBSCRIPT" %>
<%
	Response.ContentType = "video/x-ms-asf"
	Response.Write "<asx version = ""3.0"">" & vbCrLf	
		Dim MovNum
		Dim MovieURL
		MovNum = Application("MovieNumber")
		MovNum = CInt(MovNum) +1
		If MovNum = 4 Then MovNum = 1
		Application("MovieNumber") = MovNum
	Response.Write "<title>" & "Ad Number" & CStr(MovNum) & "</title>" & vbCrLf
	Response.Write "<entry>" & vbCrLf
%>
<Ref href="mms://band-name/ad<%= MovNum %>.asf" />
<%
	Response.Write "</entry>" & vbCrLf
	Response.Write "</asx>" & vbCrLf
%>
