Open protected files in browser, rather than download them

Hi

Is there a way to open protected files in a browser, yet still retain their protected status?

I can get the files to open in a browser, but then they are not protected.

We want to protect PDF documents, but show them in the browser. People will still be able to download them if they want, but the default way to access them is to view in a browser. That way they will be more likely to come to the site to always get the latest document.

thanks

Tracey
