The problem was our upgrade to Spring Security 4 from 3. Beginning with this version, the headers configuration defaults to true. This adds at least the following headers:

  • X-Content-Type-Options: nosniff
  • X-Frame-Options: DENY
  • X-XSS-Protection: 1; mode=block

Disabling the headers as described in the linked document fixes the download again. It's totally unclear to me whether this is caused by problems in IE or the other browsers, i.e., is IE right or wrong to reject the download when the headers are present. Or maybe the interpretation of those headers is fuzzy...
