Expansion on download url question

[contest man]

I want to add an ebook to my website that visitors can download. Want to know how to set up visitor download capability on my website. Hopefully this will clarify my question. Thanks for the rapid response. Sears

you just need to hotlink the file on your server, the users click it and their web browser will ask them if they wish to download it.

btw this is a java forum and your question has nothing to do with java.

I joined this forum to learn how to get the most out of my java experience.

Now, I am a raw newbie wanting to learn.

I did not understand anything you said in your email, which I thank you for. Would it make a difference if I told you I am 66 years of age and starting a new adventure in my life on the internet? I should have been more specific in the beginning.

Thanks Sears

What is the purpose of having the java program handle your downloads for you? and What email? I never sent you an email...maybe you subscribed to posts
