A domain name with more information is a URL. Hence, the domain name is part of the URL. at which part of the house you will go after entering into the house. You can say that your friend’s house address is a domain name, whereas the URL not only tells the friend’s house address (domain name) but also how you are going to communicate like talking in a separate room (secure) or in front of everyone (info can get leak). Let’s take our previous example to better understand. Whereas the domain name is part of a URL. URL tells about the method through which information should exchange, the path after reaching that website. The major difference between both is that the URL is a complete address. Don’t be confused! Difference between URL and Domain Name Wait! You might think, a seconds before I mentioned URL is the address whereas I also mentioned domain name is also address. We use it to reach to the server (trained computer) that is responsible for serving the information for that website. You can relate it to your friend’s house. information is exchanged in a secure way. 'https' is basically a secure version, i.e. A protocol is a set of rules that browser use for communication over the network. This basically tells the browser which protocol it should use. Now, we know what a URL is but we still don’t know about the parts of a URL. The web site is like the house and the URL is the address. The same thing goes here in this big web world: we have to give an address of the website which we want to access. If you want to visit your friend’s house for some work or to get information, you need their address. It is an address of the place where we want to go to interact with or find information. If you look into its full form, then it is self explanatory: it has the location of the resources which we want to access. But, today, I want my readers to get into the journey which they encounter at first when they hit any URL.Īs the topic is self explanatory - when we hit any URL then what happens? - let’s start!īefore discussing what happens after hitting the URL, we must go through what a URL actually is, and what different parts of the URL mean - right? Without wasting any time, let’s understand more about URLs. Previously, I've written articles on the fancy stuff of today’s market, i.e. Failed to initialize a udev monitor.Īnd the link opened successfully in a new chrome tab.In this article, I want my readers to get a picture of a very basic concept of the web world. Now I get these errors when clicking on the link: Could not create NETLINK socket: Permission denied (13) I added this line to the sanitized_helper profile in abstractions/ubuntu_helpers: /opt/google/chrome/crashpad_handler Pixr,Īnd reloaded the evince profile. I would appreciate any pointers that show step-by-step, how to make the necessary modification to the evince profile. I tried using aa-logprof, but I clearly need instructions that I can understand. So I need to modify the AppArmor profile for evince. So I started evince from the command line and when I tried to open a link in the document, I got this error: execv /opt/google/chrome/crashpad_handler: Permission denied (13)Īnd determined that the problem is AppArmor, which is preventing evince from invoking Chrome (but allows it to use Firefox). This is in 21.04 but I think the error is very recent, i.e. I know there are existing questions about problems with Evince opening links, but this looks like a new error.
