Is Someone Stealing Your Source Code? by Michael Southon
That's a question that worries many people on Internet. And some people go to great lengths to hide their source code.
There are several reasons you might want to conceal source code of your web pages:
=> you have web pages that rank highly in search engines and you don't want people to see your meta tags
=> you don't want people copying your web page design or java scripts
=> you want to protect your website from email harvesters and other spam utilities
But can you hide your source code?
The short answer is no - to display a web page, browser has to be able to read source, and if browser can read it, so can your visitors.
But there are ways to make it more difficult for your visitors to read your source code. Here are some of them:
(1) Adding dozens of carriage returns at top of your HTML page
This one has fooled me a couple of times. All you see is a lot of blank space - but just keep scrolling down and you'll find source code.
(2) Using frames
When you try to view source code of a page using this technique, all you see is first ten or fifteen lines of HTML. But just save page to a folder on your hard disk and then look for a sub-folder where images in that page were saved to.
