Apache Module mod_data

Description: Convert response body into an RFC2397 data URL
Status: Extension
ModuleIdentifier: data_module
SourceFile: mod_data.c
Compatibility: Available in Apache 2.3 and later

Summary

This module provides the ability to convert a response into an RFC2397 data URL.

Data URLs can be embedded inline within web pages using something like the mod_include module, to remove the need for clients to make separate connections to fetch what may potentially be many small images. Data URLs may also be included into pages generated by scripting languages such as PHP.

An example of a data URL
