sticky - technical definition

Refers to an application or service that keeps you on a Web site. For example, stock quotes, glossaries, educational material, chat rooms and similar offerings give you reason to remain on the site, while it allows the company to show you more ads or proprietary messages.

One of the major advantages of the Web is the ability to link elsewhere in an instant, but for the company that is hosting the site, it can also be a major disadvantage. See sticky connection and sticky timer.
