On IE (seen with both 6 and 7) every click that stores history information results in an access to 'blank.html' such as follows: 192.168.1.3 - - [23/Nov/2006:23:42:53 -0700] "GET /horde/dimp/js/dhtmlHistory.html?msg:INBOX:3009 HTTP/1.1" 200 1425 192.168.1.3 - - [23/Nov/2006:23:42:54 -0700] "GET /horde/dimp/js/dhtmlHistory.html?msg:INBOX:3073 HTTP/1.1" 200 1425 See, e.g., the comments located here: http://www.onjava.com/pub/a/onjava/2005/10/26/ajax-handling-bookmarks-and-back-button.html?page=6 Talk about unneeded load on the server... BTW, this doesn't happen with Mozilla (1.5 or 2). For now, I have compressed 'dhtmlHistory.html' from 1425 bytes to 169 bytes. But we need to seriously think about removing this (or at least turning this off for IE) since it may cause more problems then it fixes.

I know it's not ideal, but it's a request to a single, static HTML file - no PHP, no session locking. If this causes problems for the webserver, then that server has worse problems. And ripping out back button support just because of this seems a bit extreme to me. Fri, 24 Nov 2006 16:06:40 +0000 https://bugs.horde.org/ticket/4693#t26660 The issue is simply the fact that we are adding (potentially) unneeded load on the servers for something that theoretically shouldn't require it. But after looking around to try to find a workaround, none was found so I'm just going to go ahead and close this.
