VIRTUAL HOSTING

Link to us : http://tiny.cc/dau7r

Often abbreviated vhost, a virtual host is a provider of Web services that include server functions and Internet connection services. A virtual host is often used by companies or individuals that do not want to purchase and maintain their own Web servers and Internet connections.

A virtual host will provide its customers with domain name registration, file storage and directory services for the files that Web page is built from, e-mail services and even Web site design and creation services if the customers want someone else to build their Web sites.

A limitation of using a virtual host is that the customer shares the Web services with all the other customers of the virtual host. If the virtual host is running multiple sites off the same server, then those sites will be competing for Web server resources. Some virtual hosting providers offer co-location services and/or allow a customer to rent dedicated servers that are allocated to serve only that one customer??s needs.

Do you think virtual hosting is complicated???

Explain The Difference Between Apache and Tomcat

Content

Hello everyone!!My name is Lee Horng,Today i want to talk about what is the different between Apache and Tomcat. From week 6 pool analysis no people know what is the different between Apache and Tomcat.

The most prevalent use of the internet today is browsing. People all around the world find information by accessing data from other computers through their browser; but beyond that, people know very little. In order to communicate with the host computer, the browser would need to request pages from a http server that is run on the host computer. It would then be responsible for finding and providing you with the right pages.

An excellent and very popular web server around today is the Apache web server. It allows people who want to set-up their own web server to do so with very little trouble. Installing the Apache web server is the most basic thing you can do to support html and other related software.
The next step is to install more software that complements the web server like PHP or Tomcat.

Tomcat is another piece of software that is meant to enhance the usability and interactive experience that users experience with your website. Because Tomcat is also a server and it is also made by Apache, it is usually confused with the web server made by Apache. Just keep in mind that although they are both servers that are meant for use in the Internet, they also have separate and distinct roles to play.

Tomcat is a server that is meant to run applications that were written in Java and JSP (Java Server Pages). Java and JSP applications are type of scripts that can create dynamic tom-cat-serverpages much like PHP can. These scripts are then run on a Tomcat server where it can be accessed. It is open source software just like all the software created by Apache, and since it is open source it is also free. Tomcat offers a lot of advantages over its main competitor JRun one of which is hassle free installation; a lot of complaints have surfaced involving JRun installation.

If you are putting up a web server and you intend to have Java or JSP support on it, you might want to look at the offering that Apache has. The fact that they are made by the same group of people reduces the chances of encountering problem while operating scripts. Tomcat is currently the best at what it does and the Apache web server has also been recognized as a very competent and stable server to run. The features and stability alone are enough to sway anyone who wants to start their own servers, but the fact that both are free makes the offer irresistible. Thank You.

What is NSAPI (Netscape Server Application Programming Interface)??

Link to us: http://sn.im/27d8zn

NSAPI (Netscape Server Application Programming Interface) is an (application program interface) that is provided with Netscape Web server to help developers build faster and more complex Web-based applications by extending the server capabilities. NSAPI, the Common Gateway Interface (CGI), and the Java and JavaScript-based server API are the three components of Netscape's Internet Application Framework. NSAPI is more than CGI efficient and safe.

Through the built-in server applications, NSAPI Netscape Enterprise Services to handle the HTTP request response exchange process. Netscape Server Application Server (SAF) prepared using the NSAPI server call these functions to handle the request sent by the client. Initialized at the beginning of the server from the client to wait for HTTP requests for resources, such as HTML documents, CGI programs, or image files. Uniform Resource Identifier of the request is made by and the client and the HTTP method of composition information. Request response process includes the following six steps:


1. AuthTrans, which verifies request information (name and password, for example);
2. NameTrans, which translates the in the request into a local file system path;
3. PathCheck, which checks the validity of the path and the authorization of the user for path access;
4. ObjectType, which determines the MMIE (Multi-purpose Internet Mail Encoding) type of the resource requested by the client;
5. Service, which is the response to the client; and finally,
6. AddLog, which adds related entries to the log file.
Each step contains multiple operations, the Server Application Function (SAF) implementation. Each SAF is a result code back to the server restored to illustrate the operation is not successful. Based on this result code, the server will choose to further steps, to the current step to the next SAF or terminate the program.

Do you think NSAPI is helpful??

Introduction of JSP

Link to us: http://sn.im/26r22r

JSP(java server page) is a server-side programming technology that enables the creation of dynamic web pages and applications.IT can complete by embedding Java code into HTML,XHTML, XML, DHTML, or other document types. When a client such as a web browser makes a request to the Java application container, which is typically a web server, the static page is converted behind the scenes, and displayed as dynamic content to the viewer.It has been speculated that JSP was released to compete with PHP, a commonly used open-source programming language.JavaServer Pages technology allows Java code and select predefined actions to be inserted into static web page content. This code is compiled at runtime for each request made to the page.JavaServer Pages are usually compiled by a Java compiler.Java AJAX is form by java server page also.
This is 1 type of web file extension,did you noe what is that? If you don't know about JSP you can try and read my post and give me your impression after read my post.TQ.

Apache is a common server, itself only supports html page that is common. However, through the plug-in support for PHP, and Tomcat can also be connected (one-way connection Apache Tomcat, that is accessible through the Apache Tomcat resources).
Apache only supports static pages, but like asp, php, cgi, jsp pages to the dynamic needs of Tomcat to handle. Use Apache and Tomcat integration: If the client requests a static page, only the Apache server needs to respond to requests; If the client requests a dynamic page, it is a Tomcat server to respond to requests; because jsp is server-side interpreted code, so that integration can Tomcat service to reduce overhead.
Apache and Tomcat are independent, in the same server can be integrated.

Introduction of PHP

PHP(Hypertext Preprocessor) is a powerful language, or whether the module CGI installation, the interpreter can access files on the server, run the command and create a network connection. These functions may make the server insecure, PHP is designed for writing CGI programs than Perl or C, is to create a more secure CGI procedures. It is also available on the availability and security found a good balance. PHP may be used in many different aspects, therefore the option PHP built to facilitate the User Configuration. Although a number of options to make PHP completed a lot of work, but these options as well as the creation of the server configuration is likely to produce security issues. PHP options with syntax, with a high degree of flexibility. PHP use, can only shell user rights in the environment, create a sound server program, or the environment is strictly limited to complete its server contains (Server-side includes) without certain risk. PHP's security depend on the PHP developer.

Introduction of IIS 7(Internet Information Service7)

IIS7 (Internet Information Service 7) is a new XML-based configuration system for storing your IIS settings that replaces the metabase that was used in IIS 6.0 and earlier.This new configuration system was introduced with ASP.NET and is based on hierarchical system of management system that uses *.config files. IIS 7 support the management of several IIS servers from a single, centralized configuration file.A default installation of IIS 7 does not contain Digest authentication, so adding the setting s for Digest authentication to your ApplicationHost.config will have no effect until the Digest authentication module is installed.

According to the reference note,some setting can be delegated to Web.config files,which may overrride settings in the ApplicatioHost.config file.

I think that IIS7 easy to use to management our system, that also have a good security.Did u feel same with me?If not, can u give me your opinion.

Introduction of the SSL technology

SSL (Secure Socket Layer) was developed by Netscape to protect the security of data transmission on the Internet, the use of data Encryption technology to ensure the data on the network will not be intercepted during transmission and telephone tapping.The current specifications of safety standards is 40 bit, United States already launched 128bit restricting the exit. As long as IE 3.0 or above or Netscape browser support SSL.The current version is 3.0. It has been widely used Web browser and server authentication and encrypted data transmission.SSL protocol in the TCP/IP protocol and agreement between the various applications for data communications to provide security support. SSL protocol can be divided into two: SSL Record Protocol: It is built on a reliable transport protocol (eg: TCP) on high-level protocol provides data encapsulation, compression, encryption and other basic functions of support. Another one is SSL handshake protocol : It builds on the SSL Record Protocol, before use data transfer, authentication between the two sides, encryption algorithm, exchange of encryption keys, etc.
Do you think SSL is 100% safe??

Facebook HTTPS Secure Access To New Features

Facebook HTTPS is enabled for enhancing user's security when browsing Facebook.
HTTPS is HTTP and SSL protocol combination, can be between the computer and Web server to encrypt communications. Example if a user access to network under Wi-Fi and using simple HTTP, hackers use Firesheep, a plug-in of Firefox to obtain data. With HTTPS its more difficult.It should be noted that once HTTPS is enabled, Facebook browsing may slow down due to encryption takes longer to load the page.

Steps to enable HTTPS:
1. Go to Account in the top right corner of your Facebook page
2. From the Account drop-down menu chose Account Settings
3. Scroll down and click on Account Security.
4. Tick Secure Browsing (https) and save it.

Although may slow down browsing speed, it's more safe and secure to your account.I highly recommend it to reduce the risk of being hacked. How about you? Do you think it is better?

Apache from "a patchy server" the pronunciation, meaning that the server is full of patches, because it is free software, so someone constantly developing new features for it, to modify the original defects. Apache is characterized by a simple, fast, stable, and do the proxy server to use.
Originally, he used only for small or pilot Internet Network， Then gradually expanded to a variety of Unix systems. In particular, support for Linux perfectly. Apache has a variety of products to support SSL technology and support multiple virtual hosts.
