I'd confirm with a tool like wireshark or tcpdump that the server does,
in fact, not have a Content-Type header in the response.  But otherwise
not really - a Content-Type header is an HTTP 1.1 requirement.

If you aren't familiar with wireshark/tcpdump you can probably just
perform the request with the common curl utility, like:


$ curl -vvvv -u adam:fred123 \
     http://127.0.0.1:8080/dav/Calendar/13893410.ics
* About to connect() to 127.0.0.1 port 8080 (#0)
*   Trying 127.0.0.1... connected

.... blah blah ....
