Update
I figured out that it must be
caching problem but I can't turn cache off.
Here is my changed script:
<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript">
jQuery.ajaxSetup({
// Disable
caching of AJAX responses
cache: false
});
jQuery("#button1").click(function (e) {
window.setInterval(refreshResult, 3000);
});
function refreshResult()
{
jQuery("#divResult").load("/Home/Refresh");
}
</script>
It updates part of a web page every 3 sec. It works only once after clearing web browser cache, after that it doesn't work - requests are made to /Home/Refresh without interval of 3 seconds and nothing is displayed on the web page; subsequent requests send cookie

I am using ASP.NET MVC 2 and c#.
I have a problem with jQuery, here is how my web app works
Search.aspx web page which contains a form and jQuery script posts data to Search()
action in Home controller after user clicks button1 button.
Search.aspx:
<%@ Page Title="" Language="C#"
MasterPageFile="~/Views/Shared/Site.Master"
Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Title
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Search</h2>
<% Html.EnableClientValidation(); %>
<% using (Html.BeginForm()) {%>
<fieldset>
<div class="editor-label">
<%: Html.LabelFor(model => model.Url) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Url,
new { size = "50" } ) %>
<%: Html.ValidationMessageFor(model => model.Url) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.Location) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Location,
new { size = "50" } ) %>
<%: Html.ValidationMessageFor(model => model.Location) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.KeywordLines) %>
</div>
<div class="editor-field">
<%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%>
<%: Html.ValidationMessageFor(model => model.KeywordLines)%>
</div>
<p>
<input id ="button1" type="submit" value="Search" />
</p>
</fieldset>
<% } %>
<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript">
jQuery("#button1").click(function (e) {
window.setInterval(refreshResult, 5000);
});
function refreshResult()
{
jQuery("#divResult").load("/Home/Refresh");
}
</script>
<div id="divResult">
</div>
</asp:Content>
[HttpPost]
public ActionResult Search(WebGLSQuery queryToCreate)
{
if (!ModelState.IsValid)
return View("Search");
queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"];
Session["Result"] = null;
SearchKeywordLines(queryToCreate);
Thread.Sleep(15000);
return View("Search");
}//Search()
After button1 button is clicked the above script from Search.aspx web page runs.
Search()
action in controller runs for longer period of time. I simulate
this in testing by putting Thread.Sleep(15000); in Search()action.
5 sec. after Submit button was pressed, the above jQuery script calls
Refresh()
action in Home controller.
public ActionResult Refresh()
{
ViewData["Result"] = DateTime.Now;
return PartialView();
}
Refresh() renders this partial
<%@ Control Language="C#"
Inherits="System.Web.Mvc.ViewUserControl"
% <%= ViewData["Result"] %
The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh;
in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds.
I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work.
I would be grateful for helpful suggestions.
