online medical dictionary | definition of apache

<world-wide web, project> A open source HTTP server for Unix, Windows NT, and other platforms. Apache was developed in early 1995, based on code and ideas found in the most popular HTTP server of the time, NCSA httpd 1.3. It has since evolved to rival (and probably surpass) almost any other Unix based HTTP server in terms of functionality, and speed. Since April 1996 Apache has been the most popular HTTP server on the Internet, in May 1999 it was running on 57% of all web servers.

It features highly configurable error messages, DBM-based authentication databases, and content negotiation.

Latest version: 1.3.9, as of 01 Apr 1999.

An acronym for acute physiology and chronic health evaluation, a scoring system using routinely collected data and providing an accurate, objective description for a broad range of intensive care unit admissions, measuring severity of illness in critically ill patients. This classification system is composed of two parts: a physiology score representing the degree of acute illness and a preadmission health evaluation indicating health status before acute illness. Development of apache began in 1978 under a 3-year research grant from the u.s. Health care financing administration. Revision and streamlining resulted in apache II. Its 12 routinely measured physiological variables were later amplified to become apache III.
