hi every one , this my first post.i am kind of new to php but i learned all of ur w3schoools tutorials. great and simple thanks. By the way my question is i saw some websites they let the people download files. but if u look at the direct download link it is like hidden.if u see gmail.com if u view ur .rar extension attachment u won't see it like .rar it will be some thing different. i think they used database but even if u use database u will be abe to see it.can some one tell me how they doing it.ThanksMenan
