Set headers on internal gets

Hey

When I try to request a pdf, Orbeon call this url: xforms-server/bf4532aaf8aa2306e7c4be5f63159bfffe1e20ce/orbeon-0f68c6c7df55d5746bbb48a0c5b3ffe44523795c.css

And it fails.

The reason is that my securityfilter kills it because it dosn't have the right headers.

How can I add these headers to the call ?

Best regard
Martin
