My hunch, though I'll try to make some time to test this out
thoroughly, is that the entity is parsed initially with variables
resolved, but not per request. Variables/expressions do get expanded
for fields of course, but perhaps not for other high-level attributes?

Hmmm...perhaps my original note was a bit TLTR. Trying again:
The v1.3 docs say that one can pass one's own parameters in to DIH
via the HTTP request:
http://wiki.apache.org/solr/DataImportHandler#head-520f8e527d9da55e8ed1e274e29709c8805c8eae
SO if I have a URL like the following to dataimport:
http://localhost:8983/solr/rss/dataimport?command=full-import&foo=http%3A%2F%2Fbar.com
AND, in my data-config file I have something like:
<dataConfig>
<dataSource type="HttpDataSource" name="rss-feed" />
<document>
<entity name="article" dataSource="rss-feed"
pk="link"
url="${dataimporter.request.foo}"
processor="XPathEntityProcessor"
[blah blah blah...looks pretty much like the slashdot RSS rss-data-
config.xml]
the value of url should be filled in with 'http://bar.com', right?
Well...it's not!
I get an exception:
SEVERE: Exception thrown while getting data
java.net.MalformedURLException: no protocol: null
Which seems to indicate that the value is not getting passed. or
I'm not referring to it correctly. Or something.
Any hints would be greatly appreciated...apologies for re-spamming
the list with my desperate request,
John
