ClearSilver is a high-performance, powerful, and language-neutral HTML template system. It enforces a separation between presentation code and application logic which makes writing, debugging, and maintaining Web pages easier. It can be used from C/C++, Python, Perl, Java, and Ruby. It runs on Windows and Unix.
Douglas Thrift's Search Engine is an indexing search engine for use on small Web sites such as personal or small business sites. It is designed to be very similar to Google for end users and its output is customizable. For indexing, it supports both the Robots Exclusion Protocol and the Robots META Tag.
X2c is an Xbase compiler that creates executable programs from Xbase source on any Unix or C platform. This is accomplished by creating C source from the Xbase source, compiling, and linking with included Xbase function libraries. Whilst the C source is considered an intermediate stage for X2c, it can be used and developed as any other C source. The X2c dialect of Xbase accepts virtually all statements from Borland (was Ashton-Tate), dBASE III PLUS, Computer Associates (was Nantucket), Clipper (Summer '87), and Microsoft (was Fox Software) FoxBASE (2.1). Selected Foxpro statements are also supported.
The dkLab Apache is a patched Apache distribution for those who plan to use the Apache Web server to serve multiple separate sites working under different, fully separated, and independent Unix users. It does not require you to install any OS kernel modules or disable setuid, and works correctly and intelligently with KeepAlive turned on and MaxRequestsPerChild greater than 1.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
mod_sphinx is an Apache module which intercepts output bound for the client, whether it be from files served by the same Web server, files sent via reverse proxying, or files delivered by transparent forward proxying (outbound proxying, as in your browser's proxy setting). It opens the text and replaces a word with another word or phrase. When in regular proxy mode, it cannot modify SSL content since Apache cannot decrypt that (it would be a protocol violation).
mod_vhs is an Apache 2.2+ Web server module allowing mass virtual hosting without the need for file-based configuration. The virtual host paths are translated from any database supported by mod_ldap or mod_dbd at request time from MySQL, LDAP, PAM, or a system password file. PHP security can be basically auto-configured from the database using this module. Requests are cached by mod_ldap when configured.
