Mule ESB: Filter based on HTTP method -


i'm wondering if there way filter / route messages based on http method. i'm looking not process incoming requests have been posted options method. (this cross-origin resource share handling)

you can use mel(mule exression language - http://www.mulesoft.org/documentation/display/current/mule+expression+language+mel) query http.method param , choice router if want options request such send allowed methods so:

<choice doc:name="choice">     <when expression="#[message.inboundproperties['http.method'] == 'options']">         <http:response-builder status="200"             doc:name="http response builder(200 - options)">             <http:header name="allow" value="get" />             <http:header name="content-type" value="#[null]" />             <set-payload value="#[null]" />         </http:response-builder>     </when>     <otherwise>         <!-- else -->      </oherwise> </choice>

or can use expression filter if want drop message if not options:

<expression-filter expression="#[message.inboundproperties['http.method'] != 'options']" />
