The YAZ Proxy is highly configurable and can be used in a number of different applications, ranging from debugging Z39.50-based applications and protecting overworked servers, to improving the performance of stateless WWW/Z39.50 gateways. Among other features, it includes:

• Configurable logging
• SRU/SRW server function, to allow any Z39.50 server to also support the ZiNG protocols
• Load balancing across multiple backend servers
• Session-sharing and pre-initialization to improve performance in servers with expensive session initialization
• Configurable request filtering, to keep bad requests from reaching the server
• XML support -- MARC records can be converted to MARCXML, and XSLT-transformations allow the proxy to support arbitrary retrieval schemas in XML
• Load governor function limits requests from aggressive batch-mode clients
• Efficient multiplexing software enables small memory footprint and very high performance

NOTE: The YAZ Proxy, a complete application, is available under the GPL license. Other licensing terms are available to commercial vendors upon request.
