What is a virtual host?

Virtual host is the use of special hardware and software technology, a running on the Internet server host into a "virtual" host, each virtual host has a separate domain name, with a complete Internet server (WWW, FTP, email, etc.) function, virtual host completely independent, And can be managed by the user, in the outside view, each virtual host and a stand-alone host exactly the same. I want to settle down for small and medium-sized customers to provide quality network environment and server, and the senior management is responsible for monitoring.

What is ASP?

ASP is the abbreviation for Active Server page. It is a Web page that contains code that uses a VB script or a JScript scripting program. When the browser browses the ASP page, the Web server generates the corresponding HTML code based on the request and then returns it to the browser, so that the browser sees the dynamically generated Web page. ASP is an application developed by Microsoft to replace CGI scripts, which can interact with databases and other programs. is a simple and convenient programming tool. Once you understand the basic syntax of VBScript, you can easily write your own ASP system simply by knowing the purpose, attributes, and methods of each component. ASP's Web page file is in the format of. ASP.

What do you mean FSO?

FSO (FileSystemObject) is a Microsoft ASP's control of file manipulation, which can read, create, modify, delete directories, and file operations on the server. is a very useful control in ASP programming. However, because of the issue of permissions control, many virtual host Server FSO has become a public backdoor of this server, because customers can be in their own ASP Web page directly to the control program, thus controlling the server or even delete files on the server. So many of the industry's virtual hosting providers simply shut down the control, giving customers a lot less flexibility. I want to settle down. W2K Virtual Host Server has a high security, can let customers in their own site space arbitrary use but there is no way to harm the system or other customers to prevent the normal operation of the site.

What do you mean, CGI?

CGI is a standard for how Web servers communicate with external programs, allowing external programs to generate HTML, images, or other content, and the server is handled in the same way as HTML, images, or other content generated by non-external programs. Therefore, the CGI program only allows you to generate content and dynamic content. The reason for using CGI is that it is a well-defined and widely supported standard, and it is not possible to implement dynamic Web pages without CGI, unless some of the special methods provided in some servers (and now other technologies other than CGI are becoming 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, which is incredibly simple to use to complete a Web page that contains database functionality. In HTML files, PHP scripts (syntax similar to Perl or C language) can be referenced using special PHP tags, so that web makers do not have to rely entirely on HTML to generate Web pages. Because PHP is executed on the server side, the client does not see the PHP code. PHP can accomplish any task that a CGI script can accomplish, but its functionality depends on its compatibility with the various databases. In addition to being able to communicate using HTTP, PHP can also use IMAP, SNMP, NNTP, and POP3 protocols.

What is host hosting?

The client has complete control over the server and can independently determine the operating system and the business in which it operates.

What is a host lease?

Host rental (dedicated Hosting) that customers do not need to purchase their own servers, but can directly use my home carefully prepared a variety of Advanced Server and software systems, greatly save the procurement costs, placed in our IDC, bandwidth? Safety? Stability? System?

What is the concept of 100M space? How big is it?

For corporate web sites and even some portals, 100M is already a big enough space. If the text is simply placed, 100M is equivalent to 5000多万个 Chinese characters, if the standard Web page calculation, can accommodate 1000 pages of A4 format and 2000 pages of pictures.

Web page Upload, why not open the site?

This is divided into three different situations:

1 did not upload the webpage to the correct path according to the service provider's request

2 does not use the default file suffix name according to the service provider's request

3 The website you are applying for does not support the file type program you uploaded

Workaround:

1 service providers are generally in the open communication or website Express to the user how to upload the Web page default root directory location, such as our default root directory is/directory, if you do not upload the page to the directory will certainly not be able to access the site

2 service providers generally also have their own supported default file attributes or suffix names such as our default home page name is index.htm index.html index.asp (Windows platform), index.php, etc. so you need to check your own file name, whether the default scope is exceeded

3 If you upload an Access database file, and the site you purchased does not support database functionality, then the call to the database will fail and the page will not display, then you need to re-examine your site, if you must use the database to upgrade your site in time
　
Domain name has been registered, parsing 6 hours, the space has been opened, the Web page is also uploaded correctly, why can not show the site?

Many administrators are often "short temper", received a website opened letter, got the FTP account password, immediately want to upload, see the site has already done good results. Usually this wish can be achieved, but sometimes because the telecommunications DNS refresh did not complete the domain name in the local not resolved records, like a person without "account" can not access and upload Web pages.

Workaround:

The best way is to wait for the general telecommunications DNS refresh needs about 4-8 hours, from the domain name officially registered successfully to the global network can be normal access to at least 10-20 hours or so.

If you can't wait, there is a way to get you to complete the upload, debug, preview, and so on, the specific method is:

1 Confirm your domain name has been registered successfully, as long as you find no matter from which service provider there can not note this domain name.

2 Modify the network properties of their own computer, the TCP/IP properties of DNS designated as your domain registrar.

3 The WINDOWS98 system requires a reboot for the settings to take effect.

Network fault handling method?

Network failure with the telecommunications level of service providers, that is, to provide Web services providers room, hosting and other service providers. At present more reliable such service providers have two, one is the North China Netcom, one is the southern Chinese telecom. If their line is interrupted or the network is blocked, it may also cause the site to be inaccessible. Another possibility is that the local telecom DNS server failed or not refreshed, can also cause Web site access problems that are beyond the scope of the Web service provider's capabilities.
