[jcifs] Davenport 0.9.9b Released

[Eric]

This is an interim release; I'll be away for about a week, and won't be 
able to finish testing and fixing until after that.  In the meantime, 
this is more-or-less workable so I figured I'd float it out there. 
Release notes are listed below.

Version 0.9.9b

SUMMARY OF CHANGES:

Added support for URL rewriting based on a context base.
Added per-server authentication caching.
Disabled closing of HTTP connection upon request for authentication.
Added support for pluggable error handlers.
Added support for pluggable logging.
Added ability to specify anonymous credentials.
Added file filter framework.
Updated bundled jCIFS to version 0.9.2.


CHANGE:
     Added support for URL rewriting based on a context base.
DETAILS:

This release introduces a "contextBase" parameter, which allows 
Davenport to rewrite URLs based on a specified base URL.  This allows 
for operation in a reverse proxy scenario.  Additionally, a 
"contextBaseHeader" parameter is provided to allow the base context to 
be specified on a per-request basis.


CHANGE:
     Added per-server authentication caching.
DETAILS:

Davenport will now store authenticated credentials in the session for 
each server.  This eliminates several roundtrips and can improve 
performance significantly.


CHANGE:
     Disabled closing of HTTP connection upon request for authentication.
DETAILS:

Previous versions of Davenport closed the HTTP connection upon sending 
the request for authentication to the client.  This resulted in 
unnecessary network traffic.  This version introduces a parameter 
("closeOnAuthenticate") which allows configuration of this behavior.  By 
default, Davenport will no longer close the HTTP connection; if this 
introduces incompatibilities with certain clients, this parameter can be 
set to "true" to use the previous behavior.


CHANGE:
     Added support for pluggable error handlers.
DETAILS:

Davenport now provides a mechanism for installing handlers for errors 
presented to the servlet.  Default handlers are provided which allow 
configurable handling of authentication and IO errors.


CHANGE:
     Added support for pluggable logging.
DETAILS:

Davenport now allows for pluggable logging providers, with configurable 
severity thresholds.  See the "smbdav.Log" class for details.


CHANGE:
     Added ability to specify anonymous credentials.
DETAILS:

A parameter ("anonymousCredentials") has been added to specify an 
account used for anonymous access to SMB resources.  This will be used 
in preference to the account specified by the "jcifs.smb.client.*" 
settings.  This allows the jCIFS account to be used for 
preauthentication, while using a different account for anonymous 
browsing.  In previous versions, the jCIFS account was used for both 
purposes.


CHANGE:
     Added file filter framework.
DETAILS:

Support was added for filtering resource requests.  Extensible filters 
based on the jCIFS SmbFileFilter interface can be installed to control 
access to resources.  Out-of-box filters are provided for filtering 
based on the target server and excluding hidden resources from the 
result set.  Additionally, logical primitive filters are supplied which 
can be used to create arbitrarily complex compound filters.


CHANGE:
     Updated bundled jCIFS to version 0.9.2.
DETAILS:

jCIFS 0.9.2 includes numerous enhancements over the previous bundled 
version (0.7.19).  This includes support for SMB preauthentication, 
which resolves SMB signing issues with Windows 2003 servers.
