Cu created a applet that is download a excel file from the webserver.
Once update the excel file on the web server, applet can't download new excel file but
it reads it from its cache that is already old.
As previously emailed to the escalation alias - I don't believe we have a caching issue with the provided data. The testcase was in need of modication since xls docs buffer data and changes to a file may not mean that the size of the byte stream changes.
I modified the test case to print out the content of any requested file. The applet print out always seemed to be in sync with the file that was hosted on the webserver.
closing this as not a bug.
We check last modified to decide whether to download jar file, or image. But download excel file maybe decided by applet code, not our download manager, need to investigate.
