A dedicated server is a type of web hosting system where the client leases a web server for themselves only, and no-one else shares it. Having a secure private network can give great peace of mind, particularly for firms who have sensitive personal and financial information concerning their clients.

This also means that you can be assured having full access to the data processing power and memory of the server whenever you may need it, as opposed to being at the mercy of other users on your server who may decide to take up a lot of power or memory just when you need it most.

Many suppliers of dedicated servers will let you have unlimited bandwidth, which means that you can have as much online traffic as you want to your dedicated server without being charged any extra fees. A major advantage of leasing dedicated servers is that you can always have the latest top of the range hardware for your business applications, just like when you lease a car and change it after three months to another newer model.

The suppler will have access to the latest technology and you will not be stuck with equipment that is getting more and more out of date. Similarly the dedicated server supplier will be able to save you money. For example they will be able to broker advantageous licensing deals for associated services like control panel access.

Another major advantage of dedicated servers is the ability to choose your operating system, for example Linux or Windows, so you can have the kind of operating system that fits the needs of your business. The ability to have full remote control of your dedicated server is an important requirement. This way, you can have access to the server control panel whenever you want, from anywhere in the world. You may need for example to re-boot your server, and with this capability you can do it yourself.

Effective technical support is vital if you have a dedicated server. You need to have access to experts whenever you need them, and the best dedicated server suppliers will be able to provide this kind of support twenty four hours a day, seven days a week. These experts will be able to manage and monitor your server, particular during times when there is a lot of online traffic.

The best dedicated server suppliers will have assembled a comprehensive online knowledge base, where you can read frequently asked questions. This is a great way to get a steer on what to do, especially at the beginning of a new arrangement. It is important to work with a dedicated server suppler who has a flexible back-up capability, which can be added to as your business grows, or you amalgamate with other companies.

Most suppliers of dedicated servers will have a number of packages that they can offer you. These will be typical arrangements of hardware and levels of management and monitoring that they find works well with other clients who are similar to you in size and business needs.

Like a lot of web developers, I'm not always that disciplined when it comes to the file naming convention I use and I sometimes end up with a situation whereby I have some files that are in lowercase, some that begin with a capital, and some that are a bit of a mixture.

One web site I maintain contains about 2000 web pages and has about 20,000 hyperlinks. As you can imagine, I had one of those sinking feelings when I was told that in order to migrate the web site to a new content management system, all the file names and hyperlinks would need to be changed to lowercase.

Whenever I am presented with a problem like this, my instinct is always to write a Perl script using one or more regular expressions to solve the problem. This particular situation was no exception.

Change a string to lowercase

The following regular expression changes all the characters in a string to lowercase. The first part of the regular expression finds a hyperlink, and the second part converts the string. (Just in case this article is not displayed correctly, there should be a single backslash in front of the 'L$1').

Change a filename to lowercase

Likewise, changing a filename itself is very simple. The following two lines perform the task quite nicely:

(Again, there should be a single backslash in front of the 'L$name'.)

If you need more information on how to incorporate the above code snippets into a complete script, feel free to contact me directly.

There are a number of different browsers that you must compensate for when designing your webpage's in any format (CSS, tables etc.), some of the most common browsers are : Internet Explorer 6/ 7, Firefox and Safari. The main issues that arise with CSS design is that all browsers interpret CSS differently, for example Firefox does not understand some of the CSS commands that Internet Explorer does and vice a versa.

One of the main issues I have found when designing with CSS is a problem with margins in Internet Explorer 6. I found that when using a float on a div tag that also had a margin set, the margin would actually double and then knock the whole pages layout out. After numerous late nights and an insane amount of coffee I finally found a solution to this double margin bug. By inserting a simple line of code the double margin no longer double ! That solution is as follows, by adding this line of code to your CSS div tag 'display: inline'.

Another problem I have found with CSS in Internet Explorer 6 is a problem when trying to define a div tag that has a smaller size than the base font size. This problem again can be fixed with a simple line of code this time all we need to add is the following line of code to the div tag: 'font-size:0px'. There is also another solution to this problem that should have the same effect, because the div tag auto stretches to compensate for content overflow adding 'overflow: hidden' should also resolve the problem.

Unfortunately I have been unable to cover all of the cross browser issues that you may experience when designing with CSS, but most of the problems that you may encounter can be resolved pretty easily with simple trial and error. Happy designing!
