Necroing this old post of mine, just in case anyone comes across this
problem again. The main problem is that IE hands just the content of its
cache to Adobe Reader (or any other plugin). If the response header
explicitly tells the browser to not cache the content, no data is handed
over to the plugin. The problem can be solved by calling
session_cache_limiter('private') before session_start(). However, it's not
immediately clear when session_start() is called in a ZF app. It's probably
better to call header('Cache-Control: private') just before echoing.
BTW, this problem also occurs in 'text/xml' documents with
'Content-Disposition: attachment' header.
