Use “link” instead of “@ import” to declare the style sheet

There is evidence that this tip increases the performance of loading the style sheet (CSS) on their pages. Using the code “link” instead of “@ import” the file is loaded more quickly.

Disperse your files across multiple domains

In a large site, with large audience, you might consider putting your files in different domains. For instance, in the main domain, dedicatedserverhostingonline.com, leave the files html, asp or php, and the pictures and videos on images.dedicatedserverhostingonline.com. Thus increases paralleled downloads. Many webmasters prefer to place their scripts or images on external services like Amazon S3 or Google Ajax Libraries API relieving the load on your own server.

Reduce HTTP requests

In section page of your site can see which files are loaded. Check the JavaScript and CSS. You can join them in just a single JS file, or a single CSS file, thus avoiding multiple loads of files or script styles. The less files faster your pages will be delivered to the user.

Use GET in AJAX scripts

This technique is more geared for developers, it indicates that while using the GET method instead of POST, AJAX in your scripts, you are making a request to the server in just one step, instead of the POST which is always two steps necessary to obtain the desired data. GET transfers data at once using fewer dedicated servers.

Always Declare Dimensions of the images

One of the most neglected thing by the developers but of extreme importance. Declaring the length and height of images, videos, tables, etc., will make the browser “guess” the size of the objects which will be loading the page more slowly. On the other hand if the browser knows in advance what its size automatically reserves this space thus maintaining the consistency of the page and their texts.

There are more tips and techniques for increasing the performance of the website. Of course using these techniques periodically improves the performance of your website and therefore reduces the load on the server. Using the techniques together will be surprised with the gain that gets to you and your browsing experience, but also optimize your dedicated server hosting resources without changing to a more powerful and more expensive dedicated server.

A Cheap Dedicated Server to Handle Low Traffic Website

admin — Thu, 06 May 2010 10:18:58 +0000

If you are having a very little traffic you don’t even need a low cost server. Rather than that, you can choose cheap dedicated servers which are having Intel Pentium 4 processor with a speed of 2.4 GHz, a RAM of 512 MB and a hard disc capacity of 40 GB.

You can customize the dedicated server as per requirement. You can choose your own operating system, management and many other facilities on your desire so that your visitors will not face any problem because of break downs.

The Security of your data in the server is looked after by the operating system. Both Linux and Windows operating systems use various software’s to protect your data from hackers, spammers and many other kinds of malware.

With your cheap dedicated server too there are limitations on content of your web pages. There is restriction on copy right material. If your content needs to have copy right material you need to get written permission first. Also there is restriction on adult material too. The service providers do not allow adult material in your website unless they are legal. Another reason for not allowing adult material is that they occupy a lot of server space. This is because they normally have video sound and photographs.

In my opinion, it is always profitable to out source cheap dedicated server hosting because for a small fee you get your own server.

admin — Fri, 30 Apr 2010 12:25:53 +0000

If you are looking for more control, high reliability, enhanced security and high-performance in low budget, then moving to VPS hosting would be the right decision as it will offer you every feature and same flexibility that you expect from any dedicated server.

Having a vps hosting account enables you with all the features that you don’t get in shared hosting account, and also saves your money as it is an inexpensive web hosting solution for small and medium sized businesses. To sustain your business growth, you don’t need the power of a dedicated server, a simple VPS Hosting server can do this for you.

In VPS, you still will be sharing your server with other users like shared hosting, but the only difference is that here you will have your own virtual environment that is accessible only by you. When a web server is split into multiple small, virtual servers, the users gets all the freedom and flexibility that is offered by a dedicated server, yet in cost-effective rates.

Here are some important points to check if the VPS Hosting plan is reliable or not.

Considering the Server Hardware – Before going for any VPS web host make sure what hardware they are using in server. Make sure they use dual CPU, dual quad core Xeon processors. See if the hard drives are RAID protected or not. Minimum RAID 5 will do, if wants more faster and stable server ask for RAID 10.

Control Panels – When choosing the OS, make sure they support the control panel you want on your server. Make sure that you are provided with full root access to your VPS server, in order to install any application you want mentioned under the TOS.

For most of the small and medium sized businesses, VPS hosting is an ideal choice. Just make sure to check the reliability of that hosting provider.

Linux or Windows Dedicated Server Hosting

admin — Wed, 24 Mar 2010 14:30:51 +0000

Linux and Windows Dedicated Server Hosting platform both have their merits and demerits. Following are few important points which are to be kept in mind before choosing your hosting platform.

Security :

Most webmaster have misunderstanding that windows servers are more vulnerable than Linux servers but this is not true. Security issues are responsibility of administrator rather than OS. Even Linux server can be hacked if not handled properly.

If you have latest updated security patches and software for your server and is monitored round the clock by your administrator then there should not be any issue for your server so for security issues look for your server management staff rather them OS.

Access :

Both Linux and Windows Dedicated Servers Hosting plans offer you server access via FTP. Linux offers you SSH and telnet access whereas Windows hosting supports telnet and RPD for accessing server.

Databases :

Microsoft owned databases such as MS Access, MSSQL 2000, MSSQL 2005 etc are supported on Windows Hosting Plans where as MySQL is suited for Linux Hosting, although MySQL can be used with Windows Hosting too.

Cost :

Comparatively cost of Linux Dedicated Server hosting is cheaper then Windows Dedicated Server hosting. As Linux is open source and is free thus overall cost for Linux hosting gets reduced so it’s most preferred hosting platform. There was a time where operating systems made a big difference. Currently, most platforms are supported on both Linux and Windows.

Dedicated Hosting or VPS Hosting?

admin — Thu, 18 Mar 2010 00:57:28 +0000

It is very hard to choose a web hosting provider and further to choose a web hosting plan which will suit your requirements. Before purchasing a package it is very important for a customer to know each and every feature of the hosting package and also how it works. Shared hosting is for those who are new in business. Two of the best options available for the medium and small size businesses are Dedicated and VPS (Virtual Private Server). Which of them is better hosting package lets see:

Virtual Private Hosting

It can be understood as a hybrid plan of Shared and Dedicated Hosting. Dedicated hosting is costly and is not affordable by most of the small business. Shared hosting is cheap, not only in price but also in quality. That’s where VPS comes into action. VPS shares qualities from both shared and dedicated. It looks like shared since the server is shared by multiple users. Also VPS is like dedicated hosting as you can enjoy all the features and advantages of a dedicated server. A software divides a dedicated server into many small parts, each part acts like a dedicated server. This whole process is called virtualization. In simple words VPS hosting is like using dedicated hosting with less resources on a lower price.

Dedicated Server Hosting

Dedicated Server can be called as king of all the servers. A host provides you with one of the server placed in their data center. Two most dedicated hosting available in market are managed and unmanaged dedicated hosting, the first being more famous. If you choose to go for managed dedicated hosting, then hosting company will take care of all the maintenance and look after of your servers. However if you choose the unmanaged one then you will have to maintain your server on your own. Although unmanaged is a bit cheaper then managed dedicated hosting but mostly people prefer managed. Dedicated servers are most suitable for the website which expects huge traffic and do not want to compromise with the quality. All the resources like disk space and bandwidth are in very huge on a dedicated server and all the resources are completely dedicated to your site, you don’t have to share it anyone. Uptime guarantee on dedicated server is 100%. To make it more secure each dedicated server have the feature of customized firewall which makes it secure from all type of malicious activities on internet.

admin — Tue, 09 Mar 2010 23:00:58 +0000

With dedicated server hosting, a client is having a server which is only dedicated to him and no one else and he is the only one who gets the complete control over the server and in comparison with shared or reseller hosting, dedicated server hosting is pretty much flexible as well as offers stability. A stable SEO Dedicated Server plays most important role in SEO, and this is the main factor to which webmasters overlook most of the time.

Choosing an OS (operating system) usually depends on the price, demands and most important, its availability. Although you can have Linux for free, but when it comes to Microsoft, the cost of running a dedicated server increases. For windows operating system you will need to pay extra fees for the software and applications you will choose. Using an operating system helps in reducing the burden of site management.

With dedicated server hosting you can update the OS, applications, monitor the server, update firewall on regular basis, update antivirus, perform security audits, backups and restoration, disaster recovery, software installations and lots more.

The service providers often charges the owners for the software they use and there are many companies who offer software with dedicated servers at cheaper rates. Multiple software’s are available but it depends on the requirement of client website and business and servers can be customized as per requirements.

TCP Wrapper on Linux Dedicated Servers

admin — Fri, 06 Nov 2009 00:22:52 +0000

TCP Wrapper actually acts as a firewall for your Linux based dedicated server hosting. The reason it is referred to a kind of firewall is the fact that the incoming packets are monitored by the TCP Wrapper. If you have a Linux dedicated server then it might be possible that a hacker attempts to login into your Linux dedicated server.

TCP Wrapper will check if the external source is authorized to connect to the server. If it is not authorized, the login permission will be denied and if it is authorized, the login attempt will be successful. For this reason, you can also call TCP Wrapper as a domain computer program. It is one of the best programs available to keep hackers away from your Linux based dedicated server hosting.

This program was basically developed as your Linux dedicated server is connected to the network and it is necessary to filter the network before the server anyone can gain access to the server. TCP Wrapper is indeed a very good program, however, you can read below to find out how does it work.

When someone tries to login into the server, â€œ/etc/hosts.allowâ€ is checked for an entry file. If it is present, it is possible to continue. Even if this is not found, it is possible to continue. However, â€œ/etc/hosts.denyâ€ file is checked. If there are no matches found this time too, you will be able to continue, however, if a match is found this time, you won’t be able to continue and the service will be blocked.

For better understanding about this, you can go through the below example:

Example â€œ/etc/hosts.denyâ€ file:

SSHD: 192.168.1.1

If the above file is present, it will block access to the computer with IP address, 192.168.1.1.

Note : Itâ€™s when someone from the computer with the IP address, 192.168.1.1 tries to login via SSH, it is possible for you to run commands on your Linux dedicated server.

The below command will send an email to the email address you have registered.

sshd: 192.168.1.1: spawn (echo -e â€œ%d %h %H %uâ€| /bin/mail -s â€˜hosts.deny entryâ€™ root)

Important : It is possible for you to run commands in â€œ/etc/hosts.allowâ€ if you would like to receive emails for successful login attempts on your Linux based dedicated server hosting.
