It seems that IE download works in Horde CVS HEAD versions because in horde/lib/Browser.php there are these lines: if ($this->hasQuirk('cache_ssl_downloads')) { header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); } Any chance that this might be backported to Horde CVS RELENG version? -- -- Leena Heino (liinu at uta.fi)
