header/cache problem

[simon551]

I'm stuck. I have a page that loads json data and has a link that takes you to another page where you update info through an ajax post. I'm finding that it (the ajax post) doesn't work unless I turn off the cache on the client side. I'm trying to fix this on the server side, but it doesn't seem to be working.

I've tried putting this everywhere I can think of:

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
session_start();

I'm not really familiar with how this all works but I read something in the manual which led me to believe that would work. One note is that this is an intranet site, not a www..com site and I don't know whether that changes the script I'm supposed to invoke.

Any ideas?

what code are you using for the ajax call ? please include a random variable

[simon551]

Not sure how to include a random variable.

function submitStatus(submittype, action){		
//alert(submittype+action);
	var $status = $('#erStatus').text();
	var $etmId = $('#etmId').text();
	var $access=$('#accesslevel').text();

	if(bp==0){if ($access==1){$access=4;}}


        $.post('../postingfiles/et_statusUpdate.php',
		{ status: $status, etmId: $etmId, access: $access, action:action, submittype:submittype	},
		function(data){
		  //alert("Data Loaded: " + data);
		  $('#erStatus').text(data);
		  //run the opening script
		  //alert('trying to get the page to update now');
		  findstatus();
		  erStatus(data);
		}
        );


	if (action=='print'){
		print_r();
	}
	if(gotoindex==1){
		indexpage=$('#indexpage').text();
		//alert(indexpage);
		window.location=indexpage;
	}
}

This is the get call, the previous was the post call.

$(document).ready(function() {
$.getJSON('../sources-json/et-index.php,
    callback
);
});

I did a little checking about random variable and tried this:

$(document).ready(function() {
var d= Math.floor(Math.random()*50000);
$.getJSON('../sources-json/et-index.php?d='+d,
    callback
);
});

Still only works if I disable cache.
