Good morning. Is there a way to pass a value from an OnClick Javascript Detail Page Button to a Controller other than the controller that the button is on?

This is my JavaScript:

{!REQUIRESCRIPT("/soap/ajax/26.0/connection.js")} {!REQUIRESCRIPT("/soap/ajax/26.0/apex.js")}

var engID=window.sfdcPage.entityId var postType="statement of work";

window.location="https://rsidemo1-dev-ed--c.na24.visual.force.com/apex/VfFilePost?scontrolCaching=1&id="+engID;

I want to assign postType to a variable in the controller of the VfFilePost Page. I am new to Salesforce and programming. Any help is appreciated.
