What do you mean by "physical address"? What kind of files do you have that have you that worried about "stealing bandwidth"?
In general, anybody who visits your pages downloads your stuff - just to see it. That's not stealing - that's how the internet works.
I am new to web designing. I have a question that can I use physical adress to give the download links to my files. The files r on the webserver. SO i was wondering the way u can specify the physical adress to databases same way can I give out physical address for people to download the files for my server. Is it possible to do that. I wanted to do this so that peopel can't steal links to my files and use up my bandwith.
