That is close, but won't work for this.  the http-url script uses 


build_url basically does host + uri with some extra smarts for all the edge cases.

To have the intel framework just flag the path, you would need a variation of that script that only sets the indicator to the path:

event http_message_done(c: connection, is_orig: bool, stat: http_message_stat)
	if ( is_orig && c?$http && c$http$?uri)

You may need/want to remove any query string at the end of the path.

I don't think using Intel::URL for something that is not really a URL will cause a problem, but it is slightly confusing :-)  If you do not want that you  can add a new intel type called URL_PATH.
