Transient symbolic links.

[Anon]

I am setting up a shopping cart that can deliver downloadable products. I'd like to do this using symbolic links so the users have the option of right clicking something. Two questions. One can I generate symbolic links with PHP. If so is there a way to set it up so the links are generated when a person views a page, then removed when they exit the page? Probably require some java scripting to do an onclose or something right?

PHP supports functions such as EXEC(), so if you are on a unix system and you have the proper access rights you should be able to create Symlinks.

I wouldn't use something like javascript to signal the person has left the page, because if I disable javascript.... well you get the idea.

Instead, you'd probably have to write a crontab script to remove "old" links.

I found all that I needed for creating symlinks in the manual (whoda thunk). Anyway there are some great functions under the file system functions section for this. I guess the crontab is really the best way to handle removing the links. Thanks.
