Cache Problem Using MSIE5.0 And location.href
Hi Folks,
My solution uses browser frames. It seems to be OK with Netscape
Explorer 4.0 but I have a cache problem with MS IE 5.0. I'm not sure if
it is an MS bug or something to do with Cocoon. Any advice would be very
welcome.
One of my frames contains a directory listing. When it loads the body
onload property runs some javascript to set the location of my content
frame to the last item in the directory.
<body onload="javascript:top.cols.content.location.href=lastitem.html">
By viewing IE Internet Options > Temporary Internet Files, I can confirm
that the onload command loads the cache copy of the file instead of a
new copy from the server. This is despite the fact that the cached file
is listed as Expires=None, and Last Modified=None. Following the failed
attempt the Last Accessed time is later that the Last Checked time.
Surely this should be impossible!? Does this prove that it is an MS IE
problem or could it be the way I am using Cocoon?
Can anybody help please?
Many thanks
Peter.
P.S. Cocoon 2 is brilliant - I like it very much.
P.P.S. I'm using: NT4.0, Jdk1.3, Tomcat 3.2.1, C2rlc2.

MS IE definately has problems with caching ;-). Try setting the response
headers in your cocoon page
response.setHeader("Expires", "Mon, 01 Jan 1990 00:00:00 GMT"); //
this "hack" usually works ;-)
response.setHeader("pragma", "no-cache");
and the following meta tags in your document:
<meta http-equiv="Pragma" content="no-cache"/>
<meta http-equiv="Cache-Control" content="no-cache"/>
this should definately solve your problem (on all browsers).

RE [C2] Netscape Shows Squares For Text
Posted by Peter Hargreaves <pd...@netscape.net>.
Hi Folks,
Confirmation from an HTMLSerializer expert required please.
Further to this problem - I've now tried configuring the HTMLSerializer.
The sitemap documentation in combination with the actual sitemap suggests that
the following contains all options for configuring the HTMLSerializer - but it
doesn't seem to be effective:
<component-instance name="html"
class="org.apache.cocoon.serialization.HTMLSerializer" mime-type="text/html"
logger="sitemap.serializer.html" pool-max="32" pool-min="4" pool-grow="4">
<buffer-size>1024</buffer-size>
<doctype-public>-//W3C//DTD HTML 4.0 Transitional//EN</doctype-public>
<doctype-system>http://www.w3.org/TR/REC-html40/loose.dtd</doctype-system>
<omit-xml-declaration>true</omit-xml-declaration>
<encoding>UTF-8</encoding>
<indent>1</indent>
</component-instance>
I find that the doctype-public and doctype-system don't appear in my HTML and
the encoding parameter is not effective if I change it. I did delete my
tomcat/work directory between attempts - which might be necessary.
Could someone please confirm the correct syntax for HTMLSerializer and what is
buffer-size, and indent please?
Many thanks,
Peter.
My system is: Gateway G6-350 (392,612k RAM), NT4.0sp6, jdk-1.3.1, tomcat-4.0.1,
cocoon 2.0.2-dev, NS Nav 4.7, NS 6.1, IE 5.0
