Whenever you see . cfm as the extension of any site page instead of the usual extension . htm or.html, you will know that you are dealing with Cold Fusion Markup Language (CFML).  Though cold fusion is based on the Java platform, CFML allows web developers the benefits of Java without its technical complexity. You really don’t need to master Java scripting to be able to take advantage of Cold Fusion. Its markup language, CFML, is similar to HTML and XML, making it easy for anyone with very basic knowledge of web scripting to learn.
ColdFusion is a server-side language which means that any web page using CFML are read and interpreted by the webhost and change it into an HTML page before being sent back to the user’s browser.
Cold Fusion hosting can be quite pricier than other types of web hosting. You should consider this only if you know how to use its own unique set of tools and use it to your advantage. Cold Fusion hosting usually runs on Windows operating systems 2000/NT/2003 but you can also find support for Cold Fusion hosting on Linux and Sun.
Besides the usual factors to consider when choosing a web host company like disk space, pricing, bandwidth, guaranteed uptime, and support – you also have to consider some factors specific to Cold Fusion hosting such as restrictions on the labels, additional security problems. You should also know if the Cold Fusion webhosting company can provide database support.
A restriction on the labels is also a security issue risk. These are those that can be used to find and remove selected files from a server. For some big companies, this functionality is vital for its operation, because if files are accessed by the wrong people- a dedicated server is probably in order. It is a good thing that cold fusion hosting is offered on virtual serves, shared servers, and dedicated servers.
You should consider Cold Fusion hosting if you want the functionality of the Java platform with the installation of a relatively autonomous system software and ease of use. If your website is expected to generate an income, it is possible that its webhosting cost, in the long run, can be cost effective for you.
