Ubuntu :: Wget Downloads Corrupt Files; Gwget Doesn't Work At All?

In order to download files from a particular website, I have to include a header containing the text of a cookie, to indicate who I am and that I am properly logged in. So the wget command ends up looking something like:Code:wget --header "Cookie: user=stringofgibbrish" http://url.domain.com/content/porn.zipNow, this does work in the sense that the command does download a file of the right size that has the expected name. But the file does not contain what it should--the .zip files cannot be unzipped, the movies can not be played, etc Do I need some additional option, like the "binary" mode in the old FTP protocols?I tried installing gwget; it is easier to use, but has no way to include the --header stuff, so the downloads never happen in the first place
