[jira] Commented: (GSHELL-34) Get rid of the URLHandlerFactory

["Jason Dillon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GSHELL-34?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12532525 ] 

Jason Dillon commented on GSHELL-34:
------------------------------------

The purpose was to hook up a few custom url handlers to support vfs urls and rfile (remote-file) urls, so that when connected to a remote shell one can access local files (remote files on the client).  I can disable it for now, since I've not yet finished the rfile bits.
