gweb++ is an asynchronous event-driven Web server and reverse proxy. It is written in C++, but it doesn't make use of the STL or of any additional libraries. It supports the following event notification mechanisms: epoll (edge-triggered, Linux), kqueue (FreeBSD), port (Solaris), poll, and select. It has the following main features: HTTP/1.1, reverse proxy, FastCGI, configurable via an XML file, MIME types support, pipelining, virtual hosts, Keep-Alive, directory listing (with an optional footer file), handling of the If-Modified-Since header, HTTP ranges, logs, configurable access logs, and log rotation.
Loomes' Nested Set is a class that can be used to manage a tree of information stored in a database. It can perform several types of operations to manipulate a hierarchy of nodes that are stored in a database as table records. Currently, it can insert a root node, insert a node that is child of a given parent, delete a branch of nodes under a given node, delete a single node, rename a node, move nodes, check whether the root node exists, and retrieve the whole tree of nodes.
