Hi
i spend the whole last night figuring out the following:
IE6.0 has massive problems handling no-caching headers.
First for PHPLIB 7.2d users:
--
<? page_open(array("sess" => "mysess","auth" => "myauth"));
header ("Content-type: application/pdf");
header("Content-disposition: inline; filename=test.pdf");
$length = filesize("a.pdf");
header ("Content-length: $length");
readfile("a.pdf");
page_close();?>
If allow-caching is set to no
page_open sends a :
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-cache");
header("Cache-Control: post-check=0, pre-check=0");
header("Pragma: no-cache");
It seems as if IE6.0 is not interpreting the content-type, an content-disposion header
after the no caching header is send.
it makes no difference if you are using phplib
or your are sending the caching header manual.
workaround :
Commenting out the header lines in session.inc or add a parameter to the page_open function to turn on/off nocaching.
Further more it seems as if this is only occuring on a ssl connection.
hopefully this information will prevent others from running in that pitfall.
if i am wrong or someone discovers another solution -> please keep me informed.
testsystem was :
apache 1.3.20 + php 4.0.6 (linux 2.4.18)
regards,
niko
