Adding HTTP Headers for BOSH

Hi, I’m working on an android app that uses Smack to communicate with an XMPP server. I’m working on implementing XMPP over BOSH, but the connection manager I am attempting to communicate with requires basic authentication headers in all incoming HTTP requests. I’ve spent a lot of time perusing through documentation and google results trying to find an example or mention of how to do this. Anyone have any ideas? Does Smack support modifying the headers in the HTTP requests BOSH sends?
