Auth MemCookie is an Apache v2 authentication and authorization module based on a cookie authentication mechanism. The module doesn't do authentication by itself, but verifies if the cookie used for authentication is valid for each URL protected by the module. The module also validates whether the authenticated user has authorization to access the URL. Authentication is done externally through an authentication form page, and all authentication information necessary to the module is a stored in memcached.
Extended Virtual Synchrony for Java is a pure Java implementation of the totem single-ring protocol, which provides process group membership and reliable multicast with totally ordered messages. Because of its token-based design, this protocol is unique in achieving effective flow control, and is ideal for implementing replication in small clusters.
mod-vhost-ldap is an Apache 2.x module for storing and configuring virtual hosts from LDAP. It supports DocumentRoot, ScriptAlias, ServerName, ServerAlias, ServerAdmin, and SuexecUserGroup directives. It's built on top of mod_ldap, so it uses its caching capabilities and can be used with a threaded Apache httpd.
LdapTemplate is a framework to simplify LDAP programming in Java, built on the same principles as Spring Jdbc. The LdapTemplate class encapsulates all the plumbing work involved in traditional LDAP programming, such as creating Contexts, looping through NamingEnumerations, handling Exceptions, and cleaning up resources. This leaves the programmer free to handle the important stuff: where to find data (DNs and Filters) and what do do with it (map to and from domain objects, bind, modify, unbind, etc.).
mod_athena is an Apache-based application load balancer for large systems. It allows the HTTP server to act as a load balancer either internally to Apache's own mod_proxy (for reverse proxying), or externally to machines querying it. Arbitrary statistics are sent to the engine via a simple GET plus query-string interface, from which it will then make decisions based on chosen algorithms.
weta-dfs is a distributed file system. It is designed to be fail-safe through replications of files, fast and easy to install, platform independent, and to have fast recovery from crashes. It consists of Data Node Servers and one Meta Data Server and a java.io.File-like client API.
Graffito is a framework used to build content-based applications like CMSs, document management systems, forums, blogs, etc. It offers a complete platform for creating, managing, and publishing content in your portal or in any other kind of Java application. It integrates content repositories, workflow, collaboration, and personalization via existing open source projects and standards like WEBDAV.
