Do you know what is URL and how it works? If you are new to the Internet then you must have found the word URL very confusing.
You may have heard about it many times here and there but you will not know much about it. It must have come in your mind how to get complete information about it.
For this reason today, I thought, why should I give you complete information about it today?
So that all the troubles arising in your mind will be corrected and along with that you will get a good knowledge about it so that you will be able to tell someone about it.
So, let’s start delaying and know what is this URL and how it works.
What is URL Address?
The full form of the URL is Uniform Resource Locator. This is a formatted text string that is used in Web Browser , email clients or any other software to find a network resource.
A network resource can be any file such as Web Pages, Text Document, Graphics or Programs.
Any URL has three parts.
- Protocol Designation
- Host Name or Address
- File or Resource Location
Special characters are used to separate all these substrings. Whose Format is something like this.
protocol :// host / location
URL Protocol Substrings
This will define the type of Protocol Network protocol by which a network resource to easily access could be.
These strings are often short names followed by three special characters ” : // ” This is a typical name conversion that denotes the Protocol definition.
Typical protocols that are used are such as HTTP (http: //) , FTP (ftp: //) etc.
URL Host Substrings
With the help of Host Substring, a destination computer or network device can be identified.
Hosts come from the standard Internet Database such as DNS and which we also know by the name of IP addresses.
Hostname of many websites does not represent just a single computer but it is a group of WebServers.
URL Location Substrings
Location Substring refers to the path of any particular network that is useful in that host. Resouces mainly reside in a host directory or folder.
History of the URL
The first thing about Uniform Resource Locators was brought to the world by Tim Berners-Lee.
Who first brought this idea to everyone, an organization that provides unique locational address to all web pages.
So that they can be easily searched online . After creating HTML, many pages were created in the World Wide Web using standard language and hyperlinks with it.
After that both of them were combined. Due to which the internet got bigger and bigger day by day.
How does the URL work?
The URL has been designed in such a way that it is easy for people to remember it.
But the computer needs information to identify the right website so that it can easily find the right website.
Our Browser uses the IP of a webpage to manage it. IP which we also know as Internet Protocol. These are a series of IP numbers that look something like 184.108.40.206
Just think if we had to remember all the websites from their Ip address, then we would have been so happy.
The desires of the internet may not be as much as those in this world today. Let me tell you that not all websites have static URLs.
Some times change on time, so it is very easy to reach them. This is why we use URLs which are always the same and which is also very easy to remember.
When we type the URL of a website, then the browser then DNS, which is also called the Domain Name Server and with the help of it, converts that URL into its corresponding IP.
And with the help of which Browser reaches that website.
Different Kinds of URLs
By the way, there are many types of URLs and many different terms are used for them. I have told about some types here.
Messy : These are the types of URLs that contain a lot of numbers and letters from which any oraganization sense comes.
For example ‘ http://www.example.com/woeiruwoei909305820580 ‘. These URLs are usually generated by computers that create thousands of web pages for the same domain name.
Dynamic : These URLs have also originated from the same place where the Messy URLs came from.
These URLs are the end result of a database query which provides the content output in the result of any query. These also look like Messy URLs with characters like ?, &,%, +, =, $ .
These are used mainly in the website used by the consumer such as a shopping, travelling websites in which the user keeps changing their queries frequently, so that the answers also change.
Static : They are completely opposite to any Dynamic URL. This URL is completely hard wired with Webpage’s HTML coding. This URL never changes even if the user is requesting anything.
Obfuscated : This is a very dangerous URL which is used in Phishing Scam. As its name suggests, they are hidden.
Which is used very cleverly so that it looks completely original. So when a user clicks it, he redirects them to the Malicious Website.
Why characters are not used in the URL
We all must know that space is not used in the URL. But we should also know that according to RFC 1738, only alphanumeric characters and other characters like !, $, -, _, *, ‘, () are used in the string of the URL .
If any other characters are used then they have to be encode.
Absolute versus Relative URLs
Absolute URLs are called those in which all the sub string mentioned are used.
But in some cases only some or one location element is used, such URL is called Relative URL .
Relative URLs are used in Web Servers and Web Pages as shortcut so that the length of URL Strings can be reduced.
For example, the link of the same website has been written in the format of Relative URL and Absolute URL.
equivalent Absolute URL
The best thing that happens in this is that all the missing protocols and Host Information are filled automatically with the help of Web Server.
But keep in mind that relative URLs can be used only in those places where Host and Protocol Information can be established beforehand.
What is URL Shortening
If we talk about the standard URL of a modern website, then we will know that these are very long strings.
And sharing such long string of URLs is a difficult task. Because of which many companies have created many online translators with the help of which a full (absolute) URL can be shortened and can be used wherever it is.
There are some popular url shorteners like t.co (for Twitter) and lnkd.in (for LinkedIn) .
In addition, there are many URL Shortening Services like bit.ly and goo.gl with the help of which people all over the world are shortening their URLs for free.
Along with this, many URL Shortening Services click statistics are also offered. Apart from this, some other malicious URLs are also checked in suspicious Internet domain and inform the user.
What are Secure URLs
Secure URLs are websites that start from https: // The URL of such website is called Secure Url.
Which means that even if you enter your personal information in such a website, it gets encrypted even before it is transmitted and it is not so easy to read any hacker ‘s favor.
If you want to know in details then what is SSL, definitely read.
For the same reason, if a website asks you about your personal things such as your banking details etc.
then first of all, do not forget to check whether the Secure URL is there first.
And such a website should use some security protocol in its URL so that consumer information is not used incorrectly.
I advise you to take special care of all these things before giving any personal information.
I think by now you must have understood very well how important the Sitemap is ,
if you want that no page of your website is missed, then you have to take care that those Crawlers do not miss any page.
You can also add additional metadata such as Change Frequency and Priority.
With this you can also create a sitemap for video and image. And once you have created a Sitemap, do not forget to validate it and notify Search Engines.
