Update: I eliminated the error by removing the header "cache-control",
but now IE just displays the msi file on the screen. I think I read
somewhere that IE doesn't pay much attention to the "content-type"
header and instead tries to guess what type the content is. Is this
correct? If so, how can I trick IE into not displaying it? Should I zip
the file? Thanks.
