Yes, this is the proper behavior. App Engine production and your browser
are working correctly.
The problem is that your code is specifying the wrong MIME type. You claim
that the file is a .XLS file (which has the MIME type of "
application/vnd.ms-excel
" ) but your code is claiming a MIME type of "
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
" (wow, that's a mouthful!) which is the type reserved for Excel Open XML
format (in other words, .XLSX). You need to change this
line:
res.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
to instead set a MIME type of " application/vnd.ms-excel ".
Short version:
.XLS has a MIME type of " application/vnd.ms-excel "
.XLSX has a MIME type of "
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
"
