I am exploring whether I can write something to support this API in LabKey:

http://gmod.org/wiki/JBrowse_Configuration_Guide#JBrowse_REST_Feature_Store_API

It's an API to provide information about sequence data that would be stored in LabKey. The data is sent as fairly simply JSON, and overall it seems straightforward with one problem. JBrowse expects to pass parameters as part of the URL path, rather than as query arguments. ie:

(base)/stats/region/(refseq_name)?start=123&end=456

which is in contrast to what LabKey more naturally expects:

(base)/getSeqData?action=stats&region=(refseq_name)&start=123&end=456

Is there a good way to do the former in LabKey? I'm in java code, so all options are open. I would be making a separate module/controller, so if it were possible for my controller to hijak the process of resolving URLs very early, a form like this might work:

myserver.com/jbrowse/../../../?containerPath=XXXX&...

Have other applications needed to do something like this? Does anyone have pointers on where I should start looking? Thanks in advance.
