note 46846 deleted from function.header by tularis

Note Submitter: guvnor ---- One that tripped me up for a while... When I use PHP sessions, the following headers are sent automatically to force the browser not to cache: Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache If you are having trouble with inline PDFs etc., thses may be causing you problems. As per other notes here if you overwrite these headers before outputting your file, the download problems will go away. header('Cache-Control:'); header('Pragma:'); If you wish to retain the dynamic content, only send the above if the document you are returning is not HTML. Its well worth examining your own headers (call your PHP script from another script using get_headers() for instance) before going mad trying to fix something - better still compare the headers from your script with headers from a static web page - it might save you hours of time.
