How to do it with Apache:<br />
<br />
Use mod_headers<br />
Header set Server &quot;New Server Name Goes Here&quot;<br />
<br />
I can report my server to give you anything I want.<br />
<br />
Of course, the software might be just following permanent redirects, one to an IIS and one to an Apache based server.

Hi, all experts here. <br />
<br />
I used builtwith.com to analyse a website's technology. Let's say &quot;kornferry.com&quot;, it show two web servers are being used now. Apache 2.2 and IIS 6. How could they use two different web server to host website?<br />
<br />
Also the framwork includes J2EE and PHP and ASP.NET, as far as I know, these frameworks are different technology for different platforms, why can they use a mix?<br />
<br />
thanks.<br />

Hi, all experts here. 

I used builtwith.com to analyse a website's technology. Let's say "kornferry.com", it show two web servers are being used now. Apache 2.2 and IIS 6. How could they use two different web server to host website?

Also the framwork includes J2EE and PHP and ASP.NET, as far as I know, these frameworks are different technology for different platforms, why can they use a mix?

thanks.

why a website can use two different webserver to host their website

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

Web Servers

The Apache HTTP Server is a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards. Typically Apache is run on a Unix-like operating system, but it is available for a wide variety of operating systems, including Linux, Novell NetWare, Mac OS-X and Windows. Released under the Apache License, Apache is open-source software.

Apache Web Server

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.
