Oracle HTTP Server Components

Oracle HTTP Server Overview

Oracle HTTP Server Components

Oracle HTTP Server consists of several components that run within the same
process. These components provide the extensive list of features that Oracle HTTP
Server offers when handling client requests. Following are the major components:

■

HTTP Listener

: Oracle HTTP Server is based on an Apache HTTP listener to

serve client requests. An HTTP server listener handles incoming requests and
routes them to the appropriate processing utility.

■

Modules (mods)

: Many of the standard Apache modules are included with

Oracle HTTP Server. Oracle also includes several internal modules that are
specific to Oracle Database components.

■

Perl Interpreter

: A persistent Perl runtime environment embedded in Oracle

HTTP Server through

mod_perl

.

Oracle HTTP Server Modules

Table 1–1

identifies the modules shipped with Oracle HTTP Server. Modules extend

the basic functionality of the Web server, and support integration between Oracle
HTTP Server and other Oracle Database components. Note that the list differs from
the Apache open source distribution (given the inclusion of Oracle modules), and
that not all modules are supported by Oracle.

See Also:
