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.

what is 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.

Does the performance of each virtual host degrade due to the distribution of a machine's resources to multiple virtual hosts?

Theoretically, this is the case. However, because the computer used as a virtual host is a high performance computer, a host can support a certain number of virtual hosts, only more than this number, users will feel performance degradation. If properly configured, coupled with ultra-high speed lines, the performance of a virtual host is often better than a stand-alone host with a lower speed (such as a 256K, 1.544M) line connection. In a competitive environment, we will not increase the number of virtual hosts, sacrificing the interests of users, in pursuit of ultimate profit. Because if we do, we will lose our God.
