I am trying to dowload a file via https with curl. The site is running IIS and asp. I am able to login to the site and navigate to the download directory but when I try to download the file it errors out with Object+reference+not+set.

The download works in firefox. After I login I just paste the pathname of the file. I get a popup download prompt and then I can save the file. Any ideas?

My Curl session has the same cookies defined as firefox session.

curl -i -v --insecure -L --trace-ascii trace4.out \
-b ./cook -c ./cook -o o4 \

This is some of the header info from the trace file.

Any suggestions would be appreciated.

Here is the LiveHttp Header info from firefox. After login I just go get the file.
