Hi Yes, it looks like a good idea. I'm also going to commit a JSONP patch shortly, and you will be able to extend the inbound interceptor and update the Message headers as needed.
Message.QUERY_STRING key references the query itself, "HTTP_REQUEST" - HttpServletRequest (you can check parameters or queries), Message.PROTOCOL_HEADERS - the map of headers Thanks, Sergey On Fri, Apr 8, 2011 at 4:16 PM, KARR, DAVID (ATTSI) <[email protected]> wrote: > Just so it’s clear, I’m talking about the fact that the “Accept” header, > or any other HTTP header, cannot be sent from a “script” block.
