    Why wouldn’t they? https and www are completely different things in this URL. When looking up the structure of a URL (developer.mozilla.org/en-US/docs/Learn/Common_questions/…), what specific part is unclear? What exactly are you asking?

httpses el protocolo. Significa hyper text transfer protocol (over TLS).

Significa que navegas en sitios web y está encriptado. De forma predeterminada, el protocolo es http(sin cifrado), pero a menudo se redirige a https.

wwwes el servidor.

Puede ser cualquier cosa, pero en la mayoría de los casos, el servidor web es www. Además, los dominios lo redirigen al servidor web (si está configurado de esa manera) si no lo escribe explícitamente.

Por último, facebook.comes el dominio.

Facebook registrado para poseer el dominio facebook.com. ( .comnormalmente son sitios web comerciales) Con eso, pueden implementar servidores en direcciones que terminan .facebook.comen la forma en que se encuentran.

por ejemplo , https://www.facebook.com significa que desea hablar utilizando el protocolo https(transferencia web segura) con el wwwservidor de facebook.com.

If I want to create my own website, what should I do?

The best thing about the Web is the fact that anyone with an idea can create a Web site practically for free. A simple Web site costs about $1 a day to operate. That means that there are millions of different ideas out there being tried every day. Web sites broadcast to a gigantic world-wide audience instantly — at no other time in the history of the world has a single human being been able to reach so many people for so little money.

So let’s say that you have an idea for a Web site. What do you need to do to get started? There are a couple different levels for your idea to be operating on. Let’s take a look at them.


Let’s say that you have an idea for a Web site, and you have a cool domain name that you want to use. You aren’t sure when you will be able to get started on the site itself, but you want to make sure that nobody else gets the idea and takes that domain name. For example, let’s say that your domain name is MyIdea.com. What you want to do is check the domain name registry and make sure it’s not already taken. If it is available, you want to register that domain name (also known as “reserving” or “parking” the domain name). Registering the name gives you ownership of it. In order for you to park the domain name, it has to actually live on a server somewhere. It will usually have some sort of “Under Construction” notice that shows up when people try to access that domain name.

You need to register your domain name. There are many companies that will park your domain name on a server, and a number of them charge a fee. Verio is one of the companies that will park your domain name, and it provides a nice form that makes it easy to check for domain name availability. It only takes a couple of minutes to check and reserve a domain name.

Let’s say that you have an idea for a content site and you want to get started right away. A content site is a site that contains information for people to read or look at. The information might be words, pictures, links, etc. Yahoo! is essentially a gigantic content site. To create a content site, you need to learn HTML so you can create your pages, and then you need to find a company to host the site. That is, you need a company that will operate the Web server for your site:

  • Learn about HTML and Web pages
  • Learn about companies that can host your web site

Or maybe you have an idea for an e-commerce site. An e-commerce site lets you display the things you want to sell, take orders, process credit cards, etc. An e-commerce site is a bit more involved to set up because you have to apply for a merchant account and other commerce-related services. However, it’s not that much trouble.

Good luck creating your new site!

HTTP & WWW: Website URLs Explained

Publicado en Marketing , Desempeño , SEO por Samantha Rodriguez

Última actualización el 25 de mayo de 2022

http vs www in URLs http vs www in URLs

Protocole de transfert hypertexte (HTTP) et World Wide Web (WWW) sons acrónimos ampliamente utilizados en línea. Como probablemente sepa, ambos conceptos tienen un impacto en sus actividades de navegación diarias, ya que son une partie inhérente de todas las URL de los sitios web. Sin embargo, esta base de conocimientos no es bien comprisida por la gran mayoría de los usuarios de Internet.

HTTP et WWW ont été lancés une amende de la décennie de 1980 par Sir Tim Berners-Lee, un científico informático britannique. Su projet, le World Wide Web, involucró a HTTP y WWW trabajando juntos, desempeñando papeles cruciales en el incroyable système que damos por sentado hoy.

In this post, discusses what the URL of a website is and explains the differences between HTTP and WWW. También destacaremos cómo se usa cada uno en una URL y su importancia en los numbers de dominio del site web. ¡Empecemos!

HTTP before a WWW

As briefly mentioned previously, HTTP is the “language” standard that is used for communication between web browsers and web site servers.

WWW stands for World Wide Web, it is mainly used as a prefix. Without embargo, indicates that a particular website uses HTTP for communication.

The main difference between WWW and HTTP is that they refer to different concepts. In a few words, HTTP is the protocol that allows online communication, transfiriendo datos de una máquina a otra. WWW is the group of vinculados hypertext documents that can be seen in a web browser (like Google Chrome, Firefox and more).

Without embargo, a great similarity is both HTTP as WWW as the URL of los websites.

HTTP before a WWW to URL

Dentro de los parametros de URL, es possible to eliminate HTTP or WWW from su registrador de dominio. Sin embargo, las situaciones en las que eliminaría uno de estos elements depende de algunos factores.

As previously stated, WWW is a prefix that is used to indicate that a web site is to use HTTP to communicate. De hecho, puede mezclar y combinar prefijos, for example, http://example.com or www.example.com .

Estas diferentes URL tienen suficiente información para comunicarse entre el navegador y el servidor, por lo que ambos funcionarán sin interrupciones.

Entonces, ¿qué sucede si elige usar http://example.com como the URL of this website, pero los usuarios escriben WWW donde no es necesario? In the mayoría de los casos, the usuario will be automatically redirected to know dominio que no sea WWW. This means that you can configure a URL direction that no sea WWW without concerns.

¿Necesita WWW en las URL?

In reality, it is not necessary to use WWW en las URL. Exists with a solo proposal: identify the web direction. This is not the case with other important URLs, as well as an archive transfer protocol (FTP) server (ftp) or a notification server (news). As such, WWW can be classified as a subdominium of a larger web site.

In the mayoría of los casos, WWW no tiene ningún propósito técnico. Puede crear un dominio personalizado sin su presencia, and el site web seguirá funcionando como debería hacerlo cualquier site web.

Entonces, ¿por qué se usa WWW con tanta frecuencia? The use of WWW has existed since the creation of the Internet, and its use is generalized as a largely accidental subdominio.

El primer servidor web fue nxoc01.cern.ch. Al publicar el site web, los creadores tenían the intention that info.cern.ch fuera su página de inicio y se exclusyó WWW, as tal. The registrars of the System of Numbers of Dominion (DNS) para el servidor nunca cambiaron y el uso de WWW convirtió en una práctica standard non intencional.

As mentioned, it is possible to create a number of personalized domains without including WWW. Without embargo, hay algunas considerations a tener en cuenta.

Dominio o Direction Web sin WWW

In the mayoría de los casos, a usuario no tendrá que escribir WWW para ver su direction web o dominio. Without embargo, if you have implemented WWW to differentiate between subdominios, it is important to make sure that this site is configured to provide the redirections adecuados a los usuarios.

For other websites, adding WWW to www.example.com may lead to a redirect to example.com. Para otros, pueden ser dos páginas separadas en el mismo dominio. Su prover of alojamiento web debería poder ayudarlo a configurar to guarantee that the correct redirections are implemented.

WWW and non WWW for SEO

If you run a web site, business engine optimization (SEO) should be a high priority. Also contar con una buena strategia de SEO, puede asegurarre que su site ocupará un lugar destacado en las páginas de results del motor de búsqueda (SERP) y, como resultado, generará más tráfico .

In the last instance, if you have a number of dominio WWW or no WWW no tiene relación con su SEO. Sin embargo, lo que importa es que elijas quedarte con uno u otro (y no mezclar ambos elementos).

For SEO proposals, use a URL (ya sea WWW or no WWW) in a consistent manner in todo el site web. Esto signifies that todas las URL adjuntas a su dominio deben tener la misma designación.

Hacer esto guaranteed that the clasificaciones de su sitio web no se divida en dos dominios diferentes (por ejemplo, www.example.com y example.com ), sino que se apliquen solo a su dominio canonico.

No hay duda de que los aspects más técnicos del alojamiento web pueden ser desalentadores. Es por eso que debe elegir un proveor de alojamiento con el conocimiento, la experiencia y la tecnología para ayudarlo.
