- What is a virtual host?
Virtual host is to use special hardware and software technology to divide a computer host into “virtual” hosts. Each virtual host has an independent domain name and IP address (or shared IP address), and has a complete Internet server function. On the same hardware and the same operating system, different server programs opened for multiple users are running without interference, and each user has its own part of system resources (IP address, file storage space, memory, CPU time, etc.). Virtual hosts are completely independent from each other. In the eyes of the outside world, each virtual host and an independent host perform exactly the same. In the sense of use, it means to open up a space for you on our server hard disk, and allocate corresponding network resources for you, so that you can have your own Internet address, and your own email address [email protected], so that Internet users around the world can easily find you through your domain name. - What is bound domain name?
Binding domain name is also called “host header”. In short, if we want a domain name to visit the virtual host, we need to do the following: Step 1: resolve the IP of the domain name to the IP of the server where the virtual host is located. Second, bind the virtual host to the domain name. After these two steps, you can use the domain name to access the space. Our company adopts the independently developed HZHOST virtual host management system to provide real-time domain name binding and resolution. - What is the default homepage?
The default first page is the default document. It refers to a file that is automatically located when accessing a file directory. For example, there are many files with different names in your host space, but you want to access one of the files called index.htm by default when you enter the website www.abc.com, so you need to set the default home page to index.htm, of course, you can also set other files such as default.cgi, etc - What is ASP?
ASP is the abbreviation of active server page. It is a web page that contains code using VB script or JScript script. When the browser browses the ASP web page, the web server will generate the corresponding HTML code according to the request and then return it to the browser, so that the browser side sees the dynamically generated web page. ASP is an application developed by Microsoft to replace CGI script program. It can interact with database and other programs. It is a simple and convenient programming tool. After understanding the basic syntax of VBScript, you can easily write your own ASP system by knowing the purpose, properties and methods of each component. The format of ASP’s web file is. ASP. - What is FSO?
FSO (file system object) is a file operation control of Microsoft ASP, which can read, create, modify, delete directories and files on the server. It is a very useful control in ASP programming. However, due to the problem of permission control, FSO of many virtual host servers has become an open back door of this server, because customers can directly program this control in their ASP pages, so as to control the server or even delete the files on the server. Therefore, many virtual host providers in the industry have simply turned off this control, leaving customers with a lot of flexibility Our company’s W2k virtual host server has high security, which allows customers to use it freely in their own website space, but there is no way to harm the system or hinder the normal operation of other customers’ websites. - What is CGI?
CGI is a standard used to determine the communication mode between web server and external programs, which enables external programs to generate HTML, images or other content, while the server processes HTML, images or other content generated by non external programs in the same way. Therefore, CGI program book only enables you to generate statement content and dynamic content. The reason for using CGI is that it is a well-defined and widely supported standard. Without CGI, it is impossible to implement dynamic web pages, unless using some special methods provided in the server (now, other technologies besides CGI are gradually becoming the standard). - What is PHP?
PHP is a server-side HTML embedded script description language Its most powerful and important feature is its database integration layer. It is unbelievable and simple to use it to complete a web page with database functions. In HTML files, PHP script programs (syntax similar to Perl or C language) can use special PHP tags for reference, so Web page makers do not have to rely on HTML to generate web pages. Because PHP is executed on the server side, the client cannot see the PHP code PHP can accomplish any task that CGI script can accomplish, but its function depends on its compatibility with various databases In addition to using HTTP for communication, PHP can also use IMAP, SNMP, NNTP, POP3 protocol. - What is complete machine rental?
Dedicated hosting means that customers can directly use multiple advanced servers and software systems carefully prepared by our company without purchasing their own servers, which greatly saves the cost of procurement. Let’s take care of the bandwidth, security, stability and system in our IDC. You can even have this server in two years! - What are the components of aspemail, W3 JMail, aspmail and CDONTS?
They are all mail sending / receiving programs running on the server. ASP programs can send and receive email by connecting with them. All ASP virtual hosts in this site support W3 JMail program for free.
10.What is the HZHOST control panel?
HZHOST control panel is a set of user-oriented virtual host management system independently developed by our company. After opening the virtual host online, users can enter the HZHOST control panel to manage the status, upload, password modification, binding domain name, setting default home page, renewal and upgrading of the virtual host online All operations take effect in real time. Through the HZHOST control panel, the traditional virtual host management mode is broken, and users can freely manage the virtual host online and get the latest information of the virtual host.
11.Which is better, Win2K system or Linux system?
Which operating platform to use depends on your actual needs. If you advocate the use of free software, the cost of copyright software cannot be borne, or you prefer to use PHP programming, then we recommend that you use Linux platform. If you want to have more commercial software to support your application and like ASP programming, then Microsoft’s operating platform is your first choice.
12.Will the performance of virtual host decrease?
This is the theoretical analysis. But because the computers used as virtual hosts are all high-performance computers, a host can support a certain number of virtual hosts, only when the number is exceeded, users will feel the performance degradation. If the configuration is proper, and the ultra-high speed line is used, the performance of the virtual host is often better than the independent host connected by the lower speed line (such as 256K, 1.544m). In the competitive environment, we will not arbitrarily increase the number of virtual hosts and sacrifice the interests of users in order to pursue the ultimate profit.
