Powerful general purpose Z39.50/SRW/SRU proxy

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

  • SRW/SRU 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
  • Configurable logging
  • Efficient multiplexing software enables small memory footprint and very high performance
