ByteArrayResource's getCacheDuration( )

[Ricky]

Hi,

I want to be able to generate the byteArray (for MS - Excel report being
passed to a byteArrayResource every time the resource link is clicked. I was
trying to use getCacheDuration( ) for the same to allow for it to create
ByteArray every time the resource link is clicked on the page.

I have something like :

final ByteArrayResource modelReportByteArrayResource = new
ByteArrayResource(CONTENT_TYPE, createByteArray() ,FILE_NAME) {

            // java docs removed for clarity
            protected final int getCacheDuration() {
                return -1;  // -1 or 0 doesn't work. =(
            }
        };

// add the resource.
add(new ResourceLink(modelReportResource ));

I tried to override :
            // java docs removed for clarity
            protected final void setHeaders(final WebResponse response) {
                response.setHeader("Cache-Control", "no-cache,
must-revalidate");
            }

But I still get the same excel report over and over no matter how many times
i click the link, despite me changing some data or the stream.

Any suggestions / thoughts???
