Mark,

Take a look at the EditItemURL and EditFeedURL configuration parameters
in the User's Guide:

http://www.clapper.org/software/java/curn/docs/users-guide/#Feed_EditFeedURL

I use those parameters to change the URLs served up by various places. For
instance, consider this entry from my configuration file:

----------
[Feed_yahoo_top]
# Yahoo News item URLs are of this form:
#
#
http://us.rd.yahoo.com/dailynews/rss/topstories/*http://story.news.yahoo.com/news?tmpl=story2
...
#
# The following edit command strips off the first URL, leaving only the story
# URL. The edit command corresponds to this Perl 5 construct:
#
#        s|^http://.*\*http://|http://\|
#
URL:            ${curn:feedCacheURLPrefix}/yahoo_top_stories.xml
ForceEncoding:  ${curn:feedCacheEncoding}
EditItemURL:    's|^http://.*\*http://|http://|'
#
# All Yahoo News RSS channels seem to use the same generic title. Substitute
# a more useful one.
#
TitleOverride:          Yahoo! News Top Stories
----------

Notice the EditItemURL parameter.

Will that do what you want?

It's there, but not documented. (That's not on purpose; I just neglected to
document it.) There's a "url" element within each channel element:

   +-- channel ...................... table of contents entry for one channel
         |
         +-- title .................. [String] channel title
         |
         +-- totalItems ............. [int] total items in channel
         |
         +-- channelAnchor .......... [String] HTML anchor name for channel
         |
         +-- url .................... [String] Feed/channel URL

There's a "url" element available for each item, too.

If you look in my "HTML.ftl" FreeMarker template (it's in both the binary
jar and the source tree), you'll see that I use both ${channel.url} and
${item.url}.

I've made a note to update the Freemarker-related docs.
