application URL prefixes in the File Column plug-in

I love this plugin (I'm able to get it working mostly) but I'm running
into an issue with using it in an application with an mongrel/apache
specified application level URL prefix. This is a problem for both
uploading and viewing the file once it has been loaded. I was able to
(manually or via 2b below) load it but then the hyperlink File Column
created was still missing the prefix. It generated the following URL:

http://mydomain.com/people/photo/4/picture.name.jpg
  instead of
http://mydomain.com/PREFIX/people/photo/4/picture.name.jpg

Is there an easy way to modify (a helper function? variables in
environment.rb ?) code to get File Column to recognize the prefix? Is
this a rail's wide prefix that I could set?

Additionally I'm wishing that there were a way to define my prefix in
just one place, currently, running a rails application in a
subdirectory on the server requires no less than 3 modifications (for
me):

1)
ProxyPass /PREFIX http://127.0.0.1:8000/PREFIX (in apache)

2)
a)
   prefix: /PREFIX (in mongrel_cluster.yml)
   OR
b)
  ActionController::AbstractRequest.relative_url_root = "/PREFIX" (in
environment.rb) PLUS symbolic links in my public folder

3)
all of the hard coded links in my app/views/shared/_header html file
for example: <a href="/PREFIX/people">people</a>

There has to be an easier, more elegant way. Anybody know of one?

Thanks,

Dave

I just realized that using rails' relative_url_root (2b below) does
fix problem 3 as well... and the public folder symbolic link work
around
(detailed here: http://www.ralree.info/2006/6/15/successful-settings-for-apache-forwarding-to-mongrel)
salvages half of file column's functionality (namely: uploading).

But my main problem of *reading* these uploaded files remains. The
URL that File_Column generates still doesn't include the proper
prefix.

Any ideas? Is there any easy way I can get File_Column to use
ActionController::AbstractRequest.relative_url_root that I set in
environement.rb?

Have you looked into File Column's :base_url option?

Ah ha,

Yes, in file_column.rb
