After getting your domain name registered, paying off to your web host to get hosting for your website, and uploading your website on the web server, its time to view the final shape of your website.

Understanding DNS Propagation

Before understanding the DNS propagation, you should be aware of the working of DNS. A master DNS is created by your web hosting provider in the event when you set your website up with it. This Master DNS is recorded in the Domain Name Server of your web hosting provider. The company which registers your domain name contacts to the DNS server of your web hosting provider. Your domain name registrar does it as the master authority of your domain which you have registered with it.

How Your Website is Being Searched?

When an outsider source searches your website, it first switches to the registration database in order to find out about the DNS authority of your website. After then that it goes to the DNS sever of your web hosting service provider in order to find out the IP address of your website’s domain name. From this IP address, this outsider source locates your website and can view your website.

Caching the DNS Records

The only problem with this searching process is that when your website is searched on internet by an outside source, the search process is catalyzed, as every ISP caches it DNS records to display your website in quick time. Read the full story

A Unix shell or Linux console is a personal account which allows users access to a command prompt on another machine. We mentioned those earlier in our Post about Linux Commands , With these accounts you can login to a remote server and execute commands on it. These accounts are normally accessed via SSH. Historically we used telnet for that but now telnet is fast becoming obsolete due to security concerns. These free shell accounts can be used to practice your Linux / Unix skills as well as making most out of IRC, Email, web hosting etc.

The free Unix shell accounts listed below are all provided by not for profit organizations. The existence of these non-profit organizations is vital for Internet community.So it is not good to bring them down. (you know what I am talking about).

  2. In the filter search bar type network.http.pipelining. Be sure the value field is set to true, if not double-click to set to true. (HTTP is the application-layer protocol that most web pages are transferred with. In HTTP 1.1, multiple requests can be sent before any responses are received. This is known as pipelining. Pipelining reduces page loading times, but not all servers support it.)
