Introduction
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
