I found another interesting page on caching and http header
v's html
pragma (http://www.mnot.net/c
ache_docs/), basically it is advocating
http headers as some/most proxy doesn't look at or follow
html pragma
statements.
Looks like the 2 to use are
Last-Modified = "Last-Modified" ":"
HTTP-date, which could corrolate to
the last modified attribute of the document has to be GMT
referenced i
think
14.19 ETag
The ETag response-header field provides the current value of
the entity
tag for the requested variant. The headers used with entity
tags are
described in sections 14.24, 14.26 and 14.44. The entity tag
MAY be used
for comparison with other entities from the same resource
(see section
13.3.3).
ETag = "ETag" ":" entity-tag
ETag could cold the revision number of the document
These identifiers seem to have everthing that is needed.
something like

String contentPage = wiki.getTemplateManager().findJSP(

haven't looked into jspwiki enough to know where I can get
document last
modified or document version.
