| Additional Information | There is some known issue about Internet Explorer, no-cache headers, SSL, and downloading files using a URL.
When we upgraded from Mantis 0.18.0a3 to 0.18.1, my users reported that they couldn't access files that they attached to the bugs (we store the files in a MySQL database). I typically use Netscape 7.1, and didn't have any problem. All the users with the problem were using IE6.0.
We use SSL for our Mantis installation. I was able to reproduce the problem on my workstation when I switched to using IE6.0. I changed my config_inc.php to use a base URL of "http://" rather than "https://" (in essence, I turned off SSL for our Mantis installation) and the problem went away with IE6.0. I turned back on SSL, and the problem reappeared with IE6.0. Then, I changed core.php to comment out three of the following four lines of code:
header( 'Pragma: no-cache' );
header( 'Expires: Fri, 01 Jan 1999 00:00:00 GMT' );
header( 'Cache-Control: no-store, no-cache, must-revalidate' );
header( 'Cache-Control: post-check=0, pre-check=0', false );
Then, I was able to use IE6.0 along with SSL and download a file.
There is also a "hotfix" from Microsloth available to fix this problem in IE6.0, but there were some warnings about how the hotfix wasn't the most tested thing in the world, so we decided to keep SSL, pass on the hotfix, and hack the Mantis code.
