"There is a certain problem with search engine retrieval, and it is generally impossible for search engines to access all web pages from a ** database, or for technical reasons, search spiders do not crawl **"?

Static is the static of thought, and dynamic is the movement of human beings.

The HTML class is static, CGI, asp, PHP is a dynamic class, and there is a database.

shtml、.xml, etc. as a suffix. On HTML-formatted web pages, various dynamic effects can also appear, such as:

Animations in GIF format, flash, scrolling letters, etc., these "dynamic effects" are only visual and are different concepts from the dynamic web pages that will be introduced below.

2 (1) dynamic web pages are based on database technology, which can greatly reduce the workload of maintenance;

3) The dynamic web page is not actually a web page file that exists independently on the server, and the server returns a complete web page only when the user requests it;

(4) The "?

1. Static: The word static can be understood as stopping and not moving, and the state of not moving is called static. From a physical point of view, it is a state of rest, a state of immobility.

In addition to static, in addition to describing a state of an object, there is also a term for static in **scripting languages.

For example, the common ones are htm, html, shtml, these are the most static scripts, the use of static access to the page in addition to the access speed, and more accelerated search engine index, and the static page does not have any security risks, there is no exploitable vulnerability. The use of static to build** is beneficial and harmless to **.

2. Dynamic: dynamic, refers to the situation of change and development of (things); the active demeanor of the artistic image; Kinematic state of change or examined from the state of kinematic change.

5. Since there is no need to work through the database, the access speed of the static web page is relatively fast;

Nowadays, popular CMS supports static web pages, which is conducive to being indexed by search engines and improving access speed, but it needs to occupy a large server space, and the program consumes server resources very much when generating HTML, so it is recommended to do this kind of operation when the server is idle.

3. Dynamic web pages contain server-side scripts, so page file names are often suffix with ASP, JSP, PHP, etc. However, it is also possible to use URL static technology to make the web page suffix display as HTML. Therefore, the suffix of the page file cannot be used as the only criterion for judging the dynamic and static of **.

However, with the improvement of computer performance and the improvement of network bandwidth, the last two have been basically solved.
