Download file without opening download dialog

Question

The Problem:

I need to force the download dialog not to open in a browser when in a downloading process:

I have the server code like any other download servlet .
On the client side I have a link that points to the servlet like any other download link .

Is there a way to download automatically when clicking on the link without opening the dialog?

What I think is that it may be related to the following:

1. Server code ( Java ) ?
2. Client code ( JavaScript ) ?
3. Browser settings ?
4. Browser type ?

The Purpose behind this:

There is a website that belongs to this company where it is fortified with a high security wall clearing out the chance of downloading any virus.

The clients of this site need to have the download link saving automatically when clicked on.

Answer 1

No, you can't interact with files on HDD from a browser without notifying the user . It's a security policy.

Answer 2

If I understand well, you want the browser to download your file on a default folder without asking you where?

Well, I think that, this depends on your browser, maybe you can customize the configuration in order to set a default download folder, but, I think it is not possible to force it on the server side.
