Thanks James. We are able to add the header from our server's servlet filter code. It now appends the header for each response including static html files. It seems to be working fine so far. There are instances where it still gets blocked when a link is opened on new window. I believe we need to make sure the new window response contains the header as well, right? Also, if the header gets duplicated i.e. if the response contains the same header twice, it does not work. It looks as if the header is not sent at all. Is this how it is supposed to behave?
