Oracle HTTP Server Modules

This module provides proxy capability for FTP, CONNECT (for SSL), HTTP/0.9,
HTTP/1.0, and HTTP/1.1.

Oracle HTTP Server provides mod_rewrite as a tool for URL manipulation. A
rewriting engine based on a regular-expression parser is used by mod_rewrite to
rewrite requested URLs. The granularity of URL manipulations can be affected by
the formats of server variables, environment variables, HTTP headers, and time
stamps.

This module operates on the full URLs (including the path-info part) both in
per-server context (

) and per-directory context (.htaccess) and can

generate query-string parts on result.

The following topics are discussed in the subsequent sections:

Apache processes HTTP in phases. A hook for each of these phases is provided by
the Apache API. mod_rewrite uses two of these hooks- the URL-to-filename
translation hook which is used after the HTTP request has been read but before any
authorization starts, and the Fixup hook which is triggered after the authorization
phases and after the per-directory configuration files (.htaccess) have been read,
but before the content handler is activated.

mod_rewrite

reads the configured rulesets from its configuration structure. Server

level rulesets are best configured at startup, while directory level rulesets are
configured during the directory access of the kernel.
