Let's look at some examples to make this clearer. If the path part of the URL starts with the ' /' character, the browser will fetch that resource from the top root of the server, without reference to the context given by the current document. We can differentiate between an absolute URL and a relative URL by looking only at the path part of the URL. Because the browser already has the document's own URL, it can use this information to fill in the missing parts of any URL available inside that document. When a URL is used within a document, such as in an HTML page, things are a bit different. You don't need to include the protocol (the browser uses HTTP by default) or the port (which is only required when the targeted Web server is using some unusual port), but all the other parts of the URL are necessary. 3.The actual place on the hard drive where preferences are stored is. In your browser's address bar, a URL doesn't have any context, so you must provide a full (or absolute) URL, like the ones we saw above. 2.The page itself is stored on the server computer of. The required parts of a URL depend to a great extent on the context in which the URL is used. Let's examine what the distinction between absolute and relative means in the context of URLs. The URL standard defines both - though it uses the terms absolute URL string and relative URL string, to distinguish them from URL objects (which are in-memory representations of URLs). Thanks.What we saw above is called an absolute URL, but there is also something called a relative URL. If I’ve misunderstood your problem, please feel free to let me know.
