A dynamic website is one that changes or customizes itself frequently and automatically. Server-side dynamic pages are generated "on the fly" by computer code that produces the HTML (CSS are responsible for appearance and thus, are static files). There are a wide range of software systems, such as [[Common Gateway Interface|CGI]], [[Java Servlets]] and [[Java Server Pages]] (JSP), [[Active Server Pages]] and [[ColdFusion]] (CFML) that are available to generate [[Programming languages used in most popular websites|dynamic Web systems and dynamic sites]]. Various [[Web application framework]]s and [[Web template system]]s are available for general-use [[programming language]]s like [[Perl]], [[PHP]], [[Python (programming language)|Python]] and [[Ruby (programming language)|Ruby]] to make it faster and easier to create complex dynamic websites.

A site can display the current state of a dialogue between users, monitor a changing situation, or provide information in some way personalized to the requirements of the individual user. For example, when the front page of a news site is requested, the code running on the webserver might combine stored HTML fragments with news stories retrieved from a [[database]] or another website via [[RSS]] to produce a page that includes the latest information. Dynamic sites can be interactive by using [[HTML forms]], storing and reading back [[browser cookies]], or by creating a series of pages that reflect the previous history of clicks. Another example of dynamic content is when a retail website with a database of media products allows a user to input a search request, e.g. for the keyword [[Beatles]]. In response, the content of the Web page will spontaneously change the way it looked before, and will then display a list of Beatles products like CDs, DVDs, and books. [[Dynamic HTML]] uses [[JavaScript]] code to instruct the Web browser how to interactively modify the page contents. One way to simulate a certain type of dynamic website while avoiding the performance loss of initiating the dynamic engine on a per-user or per-connection basis is to periodically automatically regenerate a large series of static pages.
