Just to mention, this also fixed a problem with Fixefox. It did not always load the menu. But a refresh made it load. But after aplying the patch it works fine for me in both Firefox and IE.

No-cache patch fixed the problem. Thanks. P.S. Sorry for the dublicate bug report Chuck. Just never saw that amount of errors and I posted about it too fast.

The no-cache header is now the only caching header we send here. Fix will be in Horde 3.0.3. Resolving.

The changes below seems to fix the problem as far as we can test. I can't verify the original reporters problem, which was related to the Last-Modifed header, but the issue we saw under Win98/IE6 seems to be related to the missing Cache-control header. I think setting that to no-cache is the desired behavior. --- javascript.php 2005-01-19 21:45:01.000000000 +0000 +++ javascript.php 2005-01-19 21:45:17.000000000 +0000 @@ -29,9 +29,7 @@ if (!empty($app) && !empty($file) && str * don't include base.php in this file. */ Horde::compressOutput(); - $mod_gmt = gmdate('D, d M Y H:i:s', filemtime($script_file)) .

I can't, but I don't have access to Win98. But I'm confused; the original code didn't work for the original reporter. But it does for you. So which is it? Can you come up with something that works for both/

Sorry, forgot to mention it was IE 6 under Win98.

We discovered one anomaly when tried this patch: IE under Win98 fails to load the left-hand sidebar and reports that the Horde_Tree function is undefined on line 509. Backing out the changes seems to fix everything. Can anyone else confirm that behavior?

Okay. Please test this patch and let me know if I should merge it: http://cvs.horde.org/diff.php/horde/services/javascript.php?r1=1.38&r2=1.39&ty=u

I think it never worked anyway, at least the files get loaded on every page call here.

Do we want javascript that runs through services/javascript.php (and by definition requires php code, therefore) to be cached at all anymore? Anything static should be static JS, and there might be other problems caused by caching this page...

The problem turns out to be in If-Modified-Since HTTP header. This is always-failing request made by IE: GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.1 Accept: / Accept-Language: ru Accept-Encoding: gzip, deflate If-Modified-Since: Thu, 02 Dec 2004 16:27:54 GMT; length=1288 User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) Host: users.portpc-design.spb.ru Connection: Keep-Alive Cookie: Horde=8e8aa91017dc9ae1af4442dce7a2d3c0 If I skip If-Modified-Since header, evrything works fine. After deleting IE cache, scripts loads fine. After refresh it gets 500 error. When I commented out header('Last-Modified: ' . $mod_gmt); from javascript.php everything started to work just fine.

Never heard of this before, and there isn't much we can do about this. Find out why your server returns a 500 and we might be able to workaround this.

Hello. Here are the records from the httpd access log. I'm using horde 3.0.2. I cant compose new mail in imp, because javascript cant be loaded. Strangest thing is when using IE they cant be loaded at all, giving 500 error. Using Mozilla, they could be loaded periodically. The server and apache are working just fine for everything else, so I dont suspect them failing. Also, I'm using suphp and php5. Also, there are no useful information neither in the horde log (DEBUG) nor in the suphp or httpd-error logs. That's very strange too. 195.128.162.78 - - [13/Jan/2005:11:09:42 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:44 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:45 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:46 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:47 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:48 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:49 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:09:50 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)" 195.128.162.78 - - [13/Jan/2005:11:10:07 +0300] "GET /horde/services/portal/sidebar.php?httpclient=1 HTTP/1.0" 200 24380 "-" "Mozilla/5.0 (Wi ndows; U; Windows NT 5.1; en-US; rv:1.7.1) Gecko/20040707" 195.128.162.78 - - [13/Jan/2005:11:10:33 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 500 673 "-" "M ozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.1) Gecko/20040707" 195.128.162.78 - - [13/Jan/2005:11:10:35 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 200 1288 "-" " Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.1) Gecko/20040707" 195.128.162.78 - - [13/Jan/2005:11:10:36 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 200 1288 "-" " Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.1) Gecko/20040707" 195.128.162.78 - - [13/Jan/2005:11:10:37 +0300] "GET /horde/services/javascript.php?file=open_compose_win.js&app=imp HTTP/1.0" 200 1288 "-" " Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.1) Gecko/20040707"
