Why are IE6 and Firefox rendering different formats from the same URL?
I have a controller action in my Rails 2.0.2 app that looks like this:
def matrix
@shows = Show.find(:all)
@players = Player.find(:all)
respond_to do |format|
format.html
format.xls do
set_excel_headers(headers,"matrix-#{@show_year}-
#{@show_month}.xls")
end
end
end
In Firefox, this works exactly as expected - when I go to /signups/
matrix, I get the HTML format rendered. If I go to /signups/
matrix.xls, I get the Excel version.
However, when I do the same thing on IE6/XP, I get the Excel format
rendered for both. /signups/matrix tries to download the Excel file.
The log doesn''t show anything odd that I can tell:
Processing SignupsController#matrix (for 192.168.119.1 at 2008-05-14
20:03:57) [GET]
Session ID: 39a88d1fff075058276e65d67136f7dd
Parameters: {"action"=>"matrix",
"controller"=>"signups"}
[....]

0.09844 (42%) | 200 OK [http://192.168.119.1/signups/matrix]
I''m stumped - does anyone know why this would be happening?

Re: Why are IE6 and Firefox rendering different formats from the same URL?
The key to this behavior is the Accept header of the HTTP request. You can
check it in Rails with request.headers[''HTTP_ACCEPT''] (see
ActionController::AbstractRequest).
IE6 prefers MS Office content (Excel, Powerpoint, Word) over HTML:
...
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
application/vnd.ms-excel,
application/msword, application/vnd.ms-powerpoint, */*
...
(I got this from
http://www.ibm.com/developerworks/xml/library/x-tipapachexhtml/index.html
as I don''t have IE6 installed.)
So (X)HTML mimetypes don''t even appear explicitly, they''re
caught by the
wildcard */* and have the lowest priority.
Very strange, but this is how Microsoft wanted it to be. They fixed this in
the meantime. The Internet Explorer 8 beta header says simply:
Accept: */*
To be sure to get the HTML rendering, say /signups/matrix.html . I guess
you could also tinker with your HTTP server settings to give the HTML
mimetypes higher priority.

Re: Why are IE6 and Firefox rendering different formats from the same URL?
Thanks for the tip - I went in and changed application/vnd.ms-excel to application/octet-stream in the initializer/mime_types.rb file, and it seems to be performing expected behavior now.
