pls how can you protect(if possible) your external javascript and swf file/s from online thieves.
and one more thing: how can you keep a page from the browser history(using javascript)?
i once read sometimes ago that javascript's location.replace will do it but it seems it only works with older browsers.
thank you.
anybody pls?
The javascript file can be compressed ( do a search for javascript compress ), it doesn't stop anyone from stealing it though, just makes it a little more difficult to read. If you are so concerned about people finding out bits of your logic, then you should be placing this logic in a business logic layer.
SWF files have an equivalent... it's uh... uhm...
:D Actually I don't know if this would be considered an AD but my company makes obfuscation software for both JavaScript and SWF files

I hope this doesn't get me in trouble
Well it does answer the question asked. Now if it was free it would be even better but the OP didnt state he was looking for a free solution only.
I have read where swf files can be cracked quite easily.
if there are free tools its fine by me(but we all know most free apps have one or more limitations and you have to upgrade to a "pro" version to get the full functionalities).
but am also opened to "paid apps" opinion(if there are any-apart from the ones mention in ComputerJy's post).
That's why we make obfuscation software :)Quote:

Even if you obfusticate or compress the code, it's still easy to run them through a debugger or decompiler and figure out what they're doing. The same goes for trying to protect images.Quote:

If you have any kind of business logic, website settings, database information, etc setup in those JS or SWF files then you have a really big security vulnerability that needs to be resolved by changing your design, rather than trying to prevent people from accessing files that they have to access anyway.
No sane or modern web browser does this anymore and for good reason. You should NEVER modify the default behavior of the web browser. Not only is it considered malicious but it's just rude.Quote:

It's just a matter of opening one in a Flash Decompiler. Works amazingly well.Quote:

Obfuscation, by definition, doesn't do anything that should cause that. You're doing something odd :pQuote:

That's why I still have a job after version 1Quote:
