I've tried this in ZPT:

<span tal:define="dummy python:request.response.setHeader('Expires', 0); dummy python:request.response.setHeader('test', 'test')"> <h1 tal:content="python:request.response.getHeader('test')"/> <h1 tal:content="python:request.response.getHeader('a')"/> </span>

It happens that only the "test" header is displayed, the "Expires" header is not. Does Zope do somethine special with "Expires" header ? How can I set it then ? Through property ?

In principle, "Expires" is treated as any other header. There may be interactions with an HTTP accelerated Cache Manager. Though, I doubt it. -- Dieter
