There is a flag that can be set in the xavante handler that allows you
to bypass this caching.  In xavante/config.lua you can change the
following line:

    { -- wsapihandler example
      match = {"%.ws$", "%.ws/" },
      with = wsapi.xavante.makeGenericHandler (webDir)
    },

to

    { -- wsapihandler example
      match = {"%.ws$", "%.ws/" },
      with = wsapi.xavante.makeGenericHandler (webDir, true)
    },

This was added by Fabio specifically for this reason [1].

Cheers!
