Thanks Jesse, Isaiah, and everyone else that chimed in.
We've successfully got this working using urlrewrite.
Correct... I did not have the proxy type setup correcty (my co-worker
mentioned this to me too). We also found we needed version 3.2.0 of
urlrewritefilter for the proxy type to work.
Our rule looks like this
<rule match-type='wildcard'>
<from>/shindig/**</from>
<to type="proxy">http://www.shindigserver.com/shindig/$1</to>
</rule>
So now we have a webapp/container running in one domain and using
shindig server running in another. Exactly what we need.
Thanks for all the input. I'm sure I'll be back soon with my next
stumbling block, but this gets us moving in the right direction.
