28. Lu Xiaobo, CPCW, have you been distressed in how you can complete the changes to a website containing thousands of pages in the shortest time

?

So you can look at this paper

,

Perhaps you can help you. What is SSI

?

SSI is an abbreviation in English Server Side Includes

,

Translated into Chinese is the meaning of the server side. From the technical perspective

,

SSI is in the HTML file

,

You can call the command or pointer that is called by the comment line. SSI has a powerful function

,

Just use a simple SSI command to realize the content update of the entire website

,

Dynamic display time and date

,

And complex features such as SHELL and CGI scripts. SSI can be said to be the best helper for website developers who have a shortage of funds, time, and workload. SSI is initially launched on the NCSA server platform

,

Extension and strengthen in the Apache server

,

It is now possible to run on almost all servers. This article will mainly bind to the APACHE server to introduce the use of SSI. How to start SSI

?

Under the Apache server

,

You can create a direct editing server profile or create in a directory you need to use SSI

.

The HTACcess file launches SSI. Specifically

,

The process is as follows

:

,

You can edit file Access

CONF and SRM

,

Find the storage directory of the configuration file. Generally

But just find two rows starting with ADDTYPE and remove the "#" symbol of each row. Save the modification

,

Then open the file access

If the user does not want to execute a script or shell command

,

You can add keyword in the Options option row. Includesnoexec

,

This allows SSI to allow SSI

,

However, the CGI or script command cannot be performed.

(

Note

:

The latest version of the Apache server has only one profile httpd

Create a file

.

HTACCESS If the user can't access the server profile directly

,

You can use the file editor to create a named

.

HTACCESS file. note

,

There must be symbols before the file name "."

,

This way the server can know that the file is hidden file.

,

Thereby improving the security of documents

,

Avoid error operations. in

The following three lines of text need to be added in the HTACcess file

After the SHTML is completed, you can

,

This file is valid for all subdirectories. If the user wants to disable the CGI or shell command on the directory level

,

.

The Options option line in the htaccess file is added to the keyword includesnoexec. 3

SHTML or

?

Any file containing SSI before it is submitted to the client

,

All must be parsed by the server. Although this will increase the load of the server from some extent

,

But unless the user's website has millions of access users every day

,

The performance of a server does not have a significant decline. but

,

If it is not necessary to use SSI in each page

,

It doesn't have the need to let the server parses each page. If users only want to use SSI in several special pages

,

Can change the file's suffix name to

The config command config command is primarily used to modify the default settings of the SSI. among them

:

Errmsg

:

Set the default error message. In order to be able to return the user setting error information normally

,

In the html file, the errmsg parameter must be placed in front of other SSI commands.

,

Otherwise the client can only display the default error message

,

Instead of being customized by the user.

"-> 2.include command The include command can insert the text or image in other documents into the currently resolved document, is the key to the entire SSI. You can instantly update the entire site with you through the include command! The include command has two different parameters. If you use the wrong parameter update site, you will not only get the original intention, but you will get a lot of error messages. Virtual: Give the virtual path to the server side. For example:

Includes

/

HEADER

.

HTML

"-> In order to more reasonable organizational site, users can create an incrudes subdirectory in the root directory to store all the included files .virtual parameters can notify the server to include a virtual file, that is, the file and the current parsed The document is not located in the same directory, but stores in other directories. The server will find the incrudes subdirectory in the root directory based on the value of this parameter. Use this method, the user can put all the HTML documents contained in a directory in a directory And save different pages in different directories or subdirectories, depending on the relationship between each other. Regardless of which documentation can find the files contained, there will be no errors. However, there is a small problem to solve it. Generally we have added some Title and Meta tags in the page. If we specify that all pages call the same header file, it is very unflexible. When the user encounters such a problem, you can use two containing files, A section set before setting the Title tag and the part after setting the Meta tag, and any custom content can be added between the two containing files. For example:

/

Includes

/
