What does IE7 do if you right-click on the link and ask for a file save?

Can you try these 3 experiments on the agp_return_file function in plugins/role-scoper/agapetry_lib.php to help me diagnose this?

• comment out or delete the entire if ( $is_apache ) block to disable server caching.

• add the following code after the existing content-type line:

global $is_IE;

if ( $is_IE ) {

header('Content-disposition: attachment; filename=' . basename($file_path) );
}

replace the content-type line with this:

global $is_IE;
if ( $is_IE && ('application/pdf' == $type) ) {
 header('Content-Type: application/x-msdownload');

} else {
header( “Content-Type: $type” );

}

Hi Kevin,

Working on the first suggestion, file actually in "lib" subdirectory, deleted this (RS1.0.0RC4b):

    if ( $is_apache ) {
        // If web server is apache, check HTTP If-Modified-Since header before sending content
        $ar = apache_request_headers();
        if ( ! empty($ar['If-Modified-Since']) && ( strtotime($ar['If-Modified-Since']) >= $file_time ) ) {
            // 304: "Browser, your cached version of image is OK; we're not sending anything new to you"
            header( 'Last-Modified: '.gmdate('D, d M Y H:i:s', $file_time).' GMT', true, 304 );
            return;
        }
    }

I de-activated, then re-activated RS. I installed Lester Chan's wp-serverinfo (or similar) to verify I'm on Apache 2.2.3. 

I made a test post with 3 sorts of files in my uploads directory, just for some variation, and left clicked on them all, with the modified file as above.

A .gif is served normally and displays in IE

A .pdf file, no apparent change, nothing happens with left click in IE. Well a little blue status bar at the foot of IE would indicate some downlaod type activity, but no outcome from that. I tried other pdf elsewhere on the server, and that works, and also fine without RS active.

A .doc file, IE invites me to "open" or "save" or "cancel". If I "save" then I get a pop-up telling me:

"Internet Explorer cannot download [file] from [server]. Internet Explorer was not able to open this internet site. The requested site is either unavailable or cannot be found. Please try again later."

If I "open" then I seem to get invited for my https:// credentials again, and back to page with downloads on.

When I right click, save target as…I get the file cannot be written to the cache errors. I also get this with the .gif (served on left click).

I'll re-insert this deleted "if" code block, and try the next test…perhaps another day. Other work to do

I am on a secure server (https://) if that makes any difference? Firefox behaves fine with this modified code.

That worked! Thanks. Can now download from IE. But in testing, I found another problem, which may just be me not understanding things properly.

I have a number of users, who are allowed to read (and write) only in certain categories. This seems to work fine. In testing this download problem, I write a random post with some random attachments, and put it in a general category where it could be seen by all my registered users. But to hide it from them (it did not matter this did not work) I attempted to define read only from the post edit page. (The "post roles" options page seems to think this is set….)

In edit post:

I checked the box to "restrict for post - only selected groups/users are readers" and then added one of each, a user and a group, both admins. But a test user, who does not fall into this set, can see the post. What might I be doing wrong? (I have never used this facility to really narrow the readership before).

that's nailed it
