file download problem in IE

On this page, when clicking on the download icon in Internet Explorer and choosing to open it, Adobe Reader says “File not found”. Any idea of what is causing this?

Re: file download problem in IE

I can open it from IE7. Maybe it’s a setting in Adobe Reader?

Here’s another thread about this problem, apparently not really resolved yet.

Re: file download problem in IE

It sounds like this is probably caused by an IE 6 caching bug.

Try turning off the Send “Last-Modified” header? in admin > prefs > advanced > admin and see if it makes a difference.

Re: file download problem in IE

On second thoughts: Textpattern doesn’t send Cache-Control headers for file downloads, so that setting won’t make a difference.

Here are the headers sent by your server for that file download:

HTTP/1.x 200 OK
Date: Sun, 25 Feb 2007 20:10:41 GMT
Server: Apache
X-Powered-By: PHP/5.2.1
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
Content-Description: File Download
Content-Length: 268147
content-disposition: attachment; filename="parckdesign.pdf"
Connection: close
Content-Type: application/octet-stream

It’s the Cache-control: no-cache bit that probably causes the problem, as described here.

I don’t think Textpattern is sending that header in this case.

Re: file download problem in IE

Try editing textpatter/publish.php around line 131, where you see the header lines, and adding the last line here:

               $filesize = filesize($fullpath); $sent = 0;
               header('Content-Description: File Download');
               header('Content-Type: application/octet-stream');
               header('Cache-Control: private'); // add this line

Re: file download problem in IE

oh, thanks. I’ve found more about it here.

I’m going to try and hack that into the core. It should be added to svn if you ask me (and if it works).

update: yeah, it works great. The only question would be if these headers should only be trigered with pdf and xls files.

edit: ha, you doubled me. I added the following :

header(‘Expires: 0’); header(‘Pragma: cache’); header(‘Cache-Control: private’);

after line 133

G,

Can you confirm whether just the “Cache-Control:private” line by itself is sufficient to fix the problem please?
