perlbal (or something) in front of mogile?

[Dusty Leary]

Hi all,

We are moving an existing file store to mogfs.  I would like to use
the existing paths as the mogfs keys.

Right now, we have images with urls like:
http://images.imvu.com/userdata/00/12/34/45/images/foo.jpg

They are served by squid in front of apache reading from NFS, and it
has gotten very painful for the machine serving NFS.

I would like to use '/userdata/00/12/34/images/foo.jpg' as the mogfs
key to store the file.  Then, have perlbal or something listening on
userdata.imvu.com, taking a GET /userdata/00/12/34/images/foo.jpg, and
doing the mogile thing on the GET uri.

I figure this must be a common usage...  Is the perlbal plugin already written?
