[handle-dev] New Handle server version(5.3.3)

[Jane Euler <jeuler@cnri.reston.va.us>]

Hi:
We have just released a new version of the Handle server code and both 
client libraries(5.3.3).
The changes are listed below. Please go to handle.net to download the new 
version.

Let us know if you have any questions.
Thanks

=================
Changes in Version 5.3.3

* Major improvements in performance and reliability:
   * The Java library now uses a cache by default, just like the C 
library. This may result in slightly different behavior in handle clients. 
Specifically, handle updates may not be seen for up to 1 hour for 
continuously running clients. Restarting the client process will cause the 
Java library to see the updated handle.
* In both the C and Java libraries, secondary handle servers are tried 
before moving on to different protocols on failure. This results in more 
timely detection of non-responding servers and subsequently better 
perceived performance.
* In the Java library, choices between handle servers are made based on the 
performance of previous queries. Previously, this weighting occurred only 
for choosing a global server. This feature is not present in the C library.
* Server now supports dynamically growing the thread pool as needed.
* Added "urlappend" parameter in HTTP server interface, to append a 
specified string to the target redirect URL of the resolved handle.
* Numerous fixes throughout the client libraries and server.
* Update global site information
* Significant cleanup of the source distribution. The build.xml file works 
properly now, and should make it much easier to compile the Java source tree.
