Redirect POST request to another url:port while retaining its data in IIS Server

Question

I want to redirect the POST request to another url:port with POST data intact but when i am trying to do it IIS server is issuing GET request and losing the data. The web.config action method is as follows :-

<action redirectType="Temporary" type="Redirect" url="http://localhost:7070/site"> </action>

Any suggestions.
