+ Dont depend on IE to show you an attachment properly if you stream it via a + servlet. Every minor version of IE has different bugs. +
++ To guarantee it to work, instead of doing a server-side redirect + (requestdispather), try doing a client side redirect to your xls file. Thats + guaranteed to work ... (also keep in mind that *sometimes* IE makes TWO + requests for a document that is opened by an external handler .. so if your xls + production is heavy, you might have a problem.) +
