Hi, this is Wayne again with a topic “How Do URLs Work?”.
If you’ve ever, you know used the internet, which you’ve probably done considering you’re watching this video you’ve almost certainly typed in a Uniform Resource, locator or URL, to get where you’re going online. But while some are simple, like LAN, effective, ska, more whitehouse.gov, full-length URLs can look awfully confusing. Why do we need HTTP in there and what are all those amber sands question marks and pounder? Excuse me hash signs doing it’s a good question. Let’S demystify the ingredients of your typical web address, starting with the beginning of the scheme, the most familiar will probably be HTTP, which stands for hypertext Transfer Protocol, the set of commands that handles the transmission of webpages, but there are other schemes as well if you’ve ever Clicked on an email address, you might notice that the link starts with mail to a scheme that tells the browser to open up your email clients. You can fire off a message, there’s also FTP or File Transfer Protocol, which is used to send well files, as you probably guess, to and from remote servers and even IRC, which allows you to connect directly to a chatroom. The next part of a typical URL is usually a domain name.
The name of a web site like amazon.com or Microsoft, calm, v.com, net or org at the end is called a top-level domain or TLD which you can think of as the main categories that sort every web site on the Internet and help route requests through a certain Group of servers to get you to the correct website. Typically, com will indicate a commercial web site of some sort. Org indicates a nonprofit organization and there are plenty of TLDs that indicate sites associated with a certain country like US or UK. More recently, country based TLDs have been used in so-called domain hacks, like YouTube dot B II, which allows links to YouTube videos to be shorter. This doesn’t mean, however, that these site has anything to do with the kingdom of Belgium much of the rest of the URL. The part that is separated by slashes indicates the past or the specific location of page or other piece of content on the specific website. Each flash indicates another subfolder kind of like how files on your computer storage drive are organized.
As for question marks, these make a URL hard to read, but their existence actually makes a lot of sense. They indicate a query defined by the user. For example, if you type a search into Google, you’ll see your string in the results page URL after the question mark symbol, which tells the server to execute that search.
If a URL has multiple queries, these will be separated by Ambersons, showing that the browser is relaying. Multiple pieces of information to the website, such as what kind of browser you’re using or whether you were referred to a page from a certain site as you’ve ever clicked a link just to have it, send you somewhere else on the same page. That was probably done through a fragment indicated by a pound.
Sign fragments can mark specific spots on a web page, but can also indicate other things like the folder you’re. Looking at in Gmail, URLs can also incorporate a few rarely seen variations, for example, if you’re trying to access a website that requires a login and password. Some sites will allow you to just enter the username and password in the URL directly logging you in automatically convenient.
If you need to quickly share a link to a protected site, but not the best thing for security, as your browser, history will show your password in plain text and if you’ve ever visited a site based in a country that doesn’t use Latin characters like Greece or China, you might see a really weird domain name that includes X, n dot. This means that the original characters were converted into a domain name compatible with the DNS, so computers worldwide can view these pages, but if the path after the domain name contains special characters, you’ll probably see these displayed with percent-encoding, which is also sometimes used for other symbols. For example, % 24 corresponds to a dollar sign, so I hope this helped unpack the mystifying stuff you see in web addresses.
Now, if you’ll excuse me, I’ve got to get back to my IRC discussion on whether dot, ninja or dot meme are actually good top-level domains. I think they are, but some other unscrupulous people disagree.
