Starting Apache On Windows, Apache is normally run as a service. For details, see Running Apache as a Service. On Unix, the httpd program is run as a daemon that executes continuously in the background to handle requests. This document describes how to invoke httpd. How Apache Starts If the Listen specified in the configuration file is default of 80 (or any other port below 1024), then it is necessary to have root privileges in order to start apache, so that it can bind to this privileged

Reverse Proxy Guide In addition to being a "basic" web server, and providing static and dynamic content to end-users, Apache httpd (as well as most other web servers) can also act as a reverse proxy server, also-known-as a "gateway" server. In such scenarios, httpd itself does not generate or host the data, but rather the content is obtained by one or several backend servers, which normally have no direct connection to the external network. As httpd receives a request from a client, the reques

Apache Module mod_mime_magic Description: Determines the MIME type of a file by looking at a few bytes of its contents Status: Extension ModuleIdentifier: mime_magic_module SourceFile: mod_mime_magic.c Summary This module determines the MIME type of files in the same way the Unix file(1) command works: it looks at the first few bytes of the file. It is intended as a "second line of defense" for cases that mod_mime can't resolve. This module is derived from a free version of the file(1) comma

SSL/TLS Strong Encryption: An Introduction As an introduction this chapter is aimed at readers who are familiar with the Web, HTTP, and Apache, but are not security experts. It is not intended to be a definitive guide to the SSL protocol, nor does it discuss specific techniques for managing certificates in an organization, or the important legal issues of patents and import and export restrictions. Rather, it is intended to provide a common background to mod_ssl users by pulling together vario
