Thanks for that tip, Jack!

In CF apps I use the http header approach that's been mentioned already (because so far all the work has been for web apps where that's fine and desired), but I also do something like this for $.get and other cases where IE still pisses on my parade: someting = { getSometing: function(someFilePath){ $.get( someFilePath + '?' + something.noCacheToken(), function(data){ // do something with the data }); noCacheToken: function(){ return (new Date()).getTime(); } } - Jack Rick Faircloth wrote: No problem, Josh. I appreciate the help. It seems, however, that the command didn't work. That may be because the content involved wasn't directly involved in the ajax transaction, but was content being manipulated as a result of a successful ajax transaction. I really don't know...

I handle it by just adding a random number to the URL I'm requesting. i.e. $.ajax({ url: "mypage.cfm?r=" + Math.random(), data: myData, //. . . }); If you are doing a GET request, the random parameter can go into the Data then. The parameter name is arbitrary and is just ignored on the server side. This essentially forces IE to request a NEW page each time. It has the bonus that you don't need any special CF magic (such as adjusting headers). But I'd imagine setting the headers is probably better in the long run. HTH Shawn Carl Von Stetten wrote: Rick, I've had problems in the past with IE using the cached version of AJAX content instead of reloading it. The solution that generally works is to add this to the top of the .cfm page your are loading via AJAX: <cfheader name="expires" value="#now()#"> <cfheader name="pragma" value="no-cache"> <cfheader name="cache-control" value="no-cache, no-store, must- revalidate"> <Your CF code here... See if that helps. Carl On Jan 8, 5:08 pm, "Rick Faircloth" <mailto:r...@whitestonemedia.com> <r...@whitestonemedia.com> wrote: Hi, Carl...and thanks for the reply. Yes, the conditional statements are in the include_menu_index.cfm file. They determine the menu like so: <cfif isdefined("session.announcements") and session.announcements eq 1> <li><a href="cfm/announcements.cfm">Announcements</a></li> </cfif> <cfif isdefined("session.res_announcements") and session.res_announcements eq 1> <li><a href="cfm/res_announcements.cfm">RES Announcements</a></li> </cfif> etc.... FF3 does re-process the CF. IE doesn't. I confirmed that by putting this code at the top of the include_menu_index.cfm file: <cfset greeting = "Hi, Rick" /> <cfoutput>greeting = #greeting#</cfoutput> Next, I logged out, clearing the session variables, then logged back in and got "greeting = Hi, Rick" at the top of the menu. Then, before logging in as another user with different access to menu items, and therefore a different menu structure, I changed "Rick" to "Bob" and saved the include_menu_index.cfm file. I logged in as the new user, and sure enough, I got "greeting = Hi, Rick" instead of what was actually in the template, "greeting = Hi, Bob". Only when I refreshed the page did I get the correct greeting, "greeting = Hi, Bob". I've tried everything to try and figure out a way to get IE to re-render the menu, but everything I've tried has failed. I think I may have to use the cfc that processes the user's credentials to create the appropriate menu and save that content as plain HTML, then load that with jQuery. The loading seems to work with plain HTML, but without re-freshing, processing of code doesn't run. Thoughts?

If so, there may be issues with the AJAX request not using the same ColdFusion session as your main page. Also, you might check your AJAX response using Fiddler with IE and compare it to the response in Firefox using Firebug.

The problem I have is the IE (seems to be working fine in FF3) is not processing the CF code unless I do a full page refresh...then it displays the menu appropriately. Here's the jQuery...any idea how to force IE to reprocess the CF, too? $.ajax({ type: "POST", url: "login/login_processor.cfm", dataType: "json", data: formval, success: function(response){ if (response.login == "Login Successful") { $('#logstatus').empty().append("Log Out"); $('#menu').hide(); $('#menu').load("includes/include_menu_index.cfm").show(); tb_remove() }
