cocoon_2_0_3_branch StringBufferContentHandler.java
XScriptManager.java XScriptManagerImpl.java
XScriptObjectFromURL.java

XScriptVariableScope.java
Added: src/webapp/docs/samples/xscript Tag: cocoon_2_0_3_branch
test.xsp
Log:
XScript now has better variable management: variables of request,
session, global, and page scope are stored not in the XScriptManager,
but as request, session, context attributes, or as XSP page field
(respectively). Chances of memory leaks are highly reduced.
