hi, With ZFSPath product I can save a fille (a ZIP) and open it, but I can't 'open with' when I click on it; it shows up as an empty ZIP file. Any idea what's up with that? I am setting a few headers along the way: results = container['sqlSelectProductByMD5'](md5hash=id).dictionaries()[0] container.REQUEST.RESPONSE.setHeader('Content-Type', 'application/zip') container.REQUEST.RESPONSE.setHeader('Content-type', 'application/octet-stream') container.REQUEST.RESPONSE.setHeader('Content-transfer-encoding', 'binary') container.REQUEST.RESPONSE.setHeader('Content-disposition','attachment;filename=%s-%s.zip' % (results['license'], results['level'])) container.REQUEST.RESPONSE.setHeader('Content-length',len( container.reports['outgoing']['%s-%s.zip' % (results['license'], results['level'])].bytes())) return container.reports['outgoing']['%s-%s.zip' % (results['license'], results['level'])].bytes()
