MogileFs + Perlbal as Reproxy + Java Client

[Brad Fitzpatrick]

What's the raw HTTP response headers you see from both Resin (directly,
not via Perlbal), and from Perlbal (as a user would see it)?

Looking at those should illustrate exactly what's going wrong, but if it's
not clear, post it here and we can help.
