Comparison of Web Server Software
The Apache HTTP Server, an open-source project is one of more than 60 distributions of Apache, a web-server once only for the UNIX, and LINUX operating systems. Server administrators are allotted over-control of the server through the use of bindings, configuration files, configuration sections, content caching, content negotiation, dynamic shared objects (DSO), environment variables, log files, mapping URLs to the filesystem, performsance tuning, security tips, server-wide configuration, SSL/TLS encryption, Suexec execution for CGI, URL rewriting guide, and virtual hosts. The Apache HTTP server is the only server that allows for direct programming that improves upon website performance and integration.
Lighttpd web-server, an open-source project is a small web-sever footprint that allows for a lower cpu-load, and flexibility. One main difference between the Apache HTTP and Lighttpd is that Lighttpd is an all UNIX or LINUX software. Server administrators are given access through FastCGI, CGI, Auth, Output-Compression, and URL-Rewriting. Similarities between the Apache, and Lighttpd servers are that each allow server administrators over-control of the server, increasing not only for website performance, but decreasing cup-load.
Internet Information Server (IIS), a Microsoft only product is a prodigy of the the Microsoft operating systems. IIS can now engage in the URL-Rewriting modules, and PHP. However, IIS is less configurable than the Lighttpd and Apache HTTP servers. In fact, in some instances IIS fails to communicate with UNIX or LINUX DNS servers. In short the IIS web-server is designed support Microsoft products. Therefore, inherent failure to communicate between LINUX or UNIX web-servers will exist.

The Top 5 Attributes Of A Leading IT Support Company
As we progress through the era now defined by computers, computer networks have increased exponentially in their size and importance to business. Where once a sophisticated network was three computers connected together with a hub, we now have complex setups of core, access and distribution layered switching and powerful routers capable of handling the huge amounts of voice, video and data traffic that is now required to run a thriving business.
The biggest challenges for businesses then are that they often lack the expertise in house to manage this complex network. Businesses that have been around for over 20 – 30 years realize the value of IT and networks, as does any business owner worth his salt, but many are reluctant to provide the funding and focus that the network, once a non-existent cost, it now deserves.

But who to choose, we believe, is a huge challenge facing small and mid-sized businesses. (more…)
