Interesting. One thing that bothers me about the Jelly
output is that no matter how many trim="true"
attributes I use, I still get more whitespace then I
want. Then I end up spending to much time trying to
make the output pretty. So this tag would kill all
output? What would the interaction be with
jelly-tags-log? It would be nice to have something
configurable -- then you could either get the
behaviour Jelly gives now, or something more like a
scripting language, where you have to explicitly call
something like <echo> to get output.

The parameters attribute that the jelly-tags-http
library expects is a java.util.List whose elements are
org.apache.commons.httpclient.NameValuePair objects.

Yes, a more generic solution that provided a way to
easily manipulate data structures in the collections
framework would be cool and very useful.

Sure thing -- Junit is a breeze. With a few junit tags
I could easily change that last script into a Junit
test script.
