i have very little knowledge about HTTP headers, so I hope some leet webmaster in here can help me out with some pointers. im playing around with the del.icio.us API in Java. they have a URL that is accessed through HTTPS to, among others, add a post into your account. So I can retrieve the URL, but now I'm getting a 401 everytime I send it. I know nothing about security, so I'm not sure what the best way to do this is supposed to be. I'm trying to execute Code: https://userName:firstname.lastname@example.org/v1/posts/add?url=http%3A%2F%2Ftest.com&description=Summary+Test+%24+%25 but i keep getting what is the correct way to do this? how do i send over the username and password? Thanks!
