I’m trying to download a file with curl. To do these, first I must be logged in to be able to download the file. I’m trying with curl but it doesn’t work. I saw the HTTP Headers and I don’t understand why doesn’t it work. Any help is appreciated.
The commands that I use are:

curl -A 'Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.4) Gecko/20091030 Gentoo Firefox/3.5.4' --referer http://www.sportstracklive.com/signin -d 'userCredentialsForm.userCredentials.email=USERNAME%40gmail.com&userCredentialsForm.userCredentials.password=PASSWROD&_target1=Login' https://www.sportstracklive.com/signin -c cook.txt -v > pepelu

curl -A 'Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.4) Gecko/20091030 Gentoo Firefox/3.5.4' --referer http://www.sportstracklive.com/signin -b cook.txt -v http://www.sportstracklive.com/user/username > pepelu2

    This is working fine for me. 

    curl -L -c trackcookie.txt -d 'userCredentialsForm.userCredentials.email=flesk@gmail.com&userCredentialsForm.userCredentials.password=flesk&_target1=Login' https://www.sportstracklive.com/signin > track.html

    If you want any other page after you log in, you have to use -b trackcookie.txt:

    curl -L -b trackcookie.txt https://www.sportstracklive.com/user/pepelu > pepelu.html

    You always need the -L option to log on to pages with cookie based authentication, because a cookie needs to be sent as part of the headers before any html, so it needs to redirect. The exception is cookies written by javascript, but that’s another chapter.

    EDIT: You’re right. I wasn’t logged in after all. The correct way to log in is:

    curl -Lc trackcookie.txt http://www.sportstracklive.com/ > /dev/null
curl -Lb trackcookie.txt -d 'userCredentialsForm.userCredentials.email=flesk@gmail.com&userCredentialsForm.userCredentials.password=flesk&_target1=Login' https://www.sportstracklive.com/signin > /dev/null
curl -Lb trackcookie.txt http://www.sportstracklive.com/live/track/gpx?userid=31746 > mytracks.zip

    The cookie actually lives on after you log out, so it seems like it’s this sequence of server requests that determines whether the session id in the cookie corresponds to a valid session or not. I figured that out after I got to download the zip file with curl using the same session id set in Firefox when I was logged in there, but only then.
