Caching Problems with Compressed Pages in a Frameset (327716)


The information in this article applies to:

  • Microsoft Internet Explorer (Programming) 6 (SP1)
  • Microsoft Internet Explorer (Programming) 6.0
This article was previously published under Q327716

SYMPTOMS

You may intermittently receive a "Page not found" error message when you visit a Web site that contains a frameset. This error message may occur if:
  • The frames are generated dynamically.
  • The frames' addresses are the same (except for the query string portion).
  • HTTP compression is turned on.

CAUSE

When Internet Explorer caches the pages, it does not use the query string to derive the file name. When the second page's cache file is created, Internet Explorer overwrite the first page's cache file.

MORE INFORMATION

Steps to Reproduce the Problem

  1. Create the following two HTML files and put them in a folder on a Web server: Test.asp: 
    <%@ LANGUAGE="VBSCRIPT" %>
<html>
<head>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; CHARSET=utf-8" />
<META HTTP-EQUIV="Pragma" CONTENT="no-cache" />
<META HTTP-EQUIV="Expires" CONTENT="-1" />
</head>

<frameset rows="50%,50%" border="1">
<frame frameborder="1" src="test1.asp?Load=GetHTML1" />
<frame frameborder="1" src="test1.asp?Load=GetHTML2" />
</frameset>

</html>
    Test1.asp: 
    <%@ LANGUAGE="VBSCRIPT" %>
<html>
<head>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; CHARSET=utf-8" />
<META HTTP-EQUIV="Pragma" CONTENT="no-cache" />
<META HTTP-EQUIV="Expires" CONTENT="-1" />
</head>
<body>
<%
Select Case UCase(Request.QueryString("Load"))
Case "GETHTML1"
	Response.Write "PAGE 1"
Case "GETHTML2"
	Response.Write "PAGE 2"
End Select
%>
</body>
</html>
  2. Turn on HTTP compression on the server for both dynamic and static files.
  3. From a different computer, open the Test.asp page. The problem should occur. If it does not, try refreshing the page several times.
Note the META tags. You do not have to use them to to see the problem, but having them makes it easier to see the problem.
