Hiding a .JS file

 2:56 pm on Dec 13, 2002 (gmt 0)

Is it possible to hide a .JS file or at least prevent it from being downloaded when a page is saved?

There will probably not be a safe way, because the file will have to be transferred to the users computer to be executed.

You could test if the request for the .js file has a referrer from a legitimate file, and deny it otherwise, but it is not foolproof. Some browsers and proxies doesn't send the referrer header, and it can be faked.

So, something can be done, but nothing that is perfectly safe.

If you really want to protect the code, I would put it in the page and encrypt the whole page,

Still not 100% foolproof - and no SE friendly.
