I would like to know if it is legal to download the content of a website and display it in my own?
There is one way to include a website inside another:
<iframe> (w3schools description)
However, some websites decide that they don't want to get iframed. For example Google doesn't allow other websites to frame their content. This has of course certain reasons. There is a very simple option, the
X-Frame-Option that can tell a browser that it must not render a page withing a frame if it is not from the same origin as the page itself.
So far so good. Just for the sake of completeness I want to say that it's still possible to display just the content of another website. The most trivial one would be to hit
CTRL + S on my keyboard, save the website and host it on another server. A more sophisticated of course would be to write a program that does that for me. One could simply download the HTML page and embed the result into another.
I can imagine that e.g. copyright could be an issue. But what if my site states that it does not own the content etc. and that it did not modify anything and so on.
Is there a way that this could be legal?
