I am trying to cache asp.net page response on client Browser by adding following cache headers
Response.Cache.SetExpires(DateTime.Now.AddMinutes(10));
Response.Cache.SetCacheability(System.Web.HttpCacheability.Public);
With the above headers it is not working.. May I know what else to be added?
I am using jquery from client side to get the page response
I have an HTTPHandler that returns some XML. I am trying to figure out how to get this to cache in the browser, as if it were a static XML file.
I've tried this along with a few other variations and other Cache options, but nothing I do seems to make it cache (according to Fiddler).
how I can cache the output on the client's browser?

The dilaogbox that offers me to save the file shows incorrect chars if documentFileName has name not in ASCII format. What I'm supposed to do to have the file name displayed correctly in this dialogbox and to have this file opened under the same name in MS Word, Excel whatever else?
I have a web form which does a full page postback when a button is clicked. This is caused by an update panel trigger. Client-Side: When the button is clicked, an animation gif is displayed Server-Side: When the button is clicked, the server side event changes the content type to excel, binary writes out excel content (byte array) and does Response.Flush() and Response.End() Client-Side: User is asked to either open or download the excel file. Animation gif is still displayed.
Question: How can I detect client side (using jQuery or Ajax) that the response has been completed. There is no page postback because the code-behind has cut off the response by using Response.End().
I have some code that is used to replace certain page output with other text. The way I accomplish this is by setting the Response.Filter to a Stream, Flushing the Response, and then reading that Stream back into a string. From there I can manipulate the string and output the resulting code. You can see the basic code for this over at [URL] However, I noticed that Page Caching no longer works after the first Response.Flush call.
I put together a simple ASP.NET WebApp as an example. I have a Default.aspx with an @OutputCache set for 30 seconds. All this does is output DateTime.Now.ToLongTimeString(). I override Render. If I do a Response.Flush (even after the base.Render) the page does not get cached. This is regardless of any programmatic cacheability that I set. So it seems that Response.Flush completely undermines any page caching in use. Why is this?
extra credit: is there a way to accomplish what I want (render output to a string) that will not result in Page Cache getting bypassed?
ASPX Page:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestCacheVsFlush._Default" %>
<%@ OutputCache Duration="30" VaryByParam="none" %>
<%= DateTime.Now.ToLongTimeString() %>
Code-behind (Page is Cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
Code-behind (Page is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Flush();
}
Code-behind (Page still is not cached):
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
Response.Cache.SetCacheability(HttpCacheability.Server);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(30));
Response.Flush();
}
I'm implementing Outputcache in my application and it works fine, but the first time always take a lot to load and the next following request will be faster...
I would like to know if there is a way to initiate the page caching on the server side and serve the cached page upon the very first request, rather than have it triggered by the user one first time.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

View 4 RepliesIn my application I need to pass a string value from the server side(.aspx.cs) to a function in the client side (.aspx) page.
View 4 RepliesI have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
Let's say you had a page like an eBay auction, where some of the content (top bidder, bids, history, etc) needed to be up to date but other sections would likely never change, like the description. I'd like to know the "right" method for getting that static section cached.
The "cheezy" solution would be to code it up in a separate javascript .js file as a bunch of "document.writeln()" calls, but that's plain evil and ugly.
If I made it a Content section of a master page, that might get it cached at the server, but the client has no way to know that this particular section of the page will never change.
I could IFRAME it but I don't always know the dimensions.
I'm sure this has all been done before, and as much as I love my own wheels, I'd rather not reinvent this one :-)

I have 4 forms in my asp.net mvc view.I have enabled client side validation on each by put <% Html.EnableClientValidation(); %> Above Html.BeginForm()of each form.The issue is that regardless of the fact that I've specified ID's for the forms the first form on the page gets validated whenever I click submit of the other forms.
Is this usage supported?
1.Viewstate is only for single page

is there any other option to use Client side state management for multiple page like viewstate encryption.. ?
I am using JQuery for all of my client side validation and Asp.net validator controls for all of my server side validation. I am using an errorlabelcontainer to store the client side validations in a summary at the top of the page, which is the requirement. All works well. My problem is, I want to display the server side asp.net errors in the same errorlabelcontainer OR display all of the client side errors in the validation summary. Either way, Both errors need to be in the same place/div. Any ideas on how to do this? I thought of maybe using the asp.net validation summary as the errorcontainer in JQuery, but I cannot find the summary. This is what I have right now.
$("#aspnetForm").validate(
{
onkeyup: false,
errorLabelContainer: $("ul", $("#FormErrors")),
wrapper: "li"
});

I have a page that downloads a dataset and streams the output to an Excel file by modifying the response headers.
I want to write an AJAX call on the client side that can display a modaldialog while the file is being generated and dismiss the modaldialog when the file has been fully rendered.
I can turn the dalog on when the user clicks a link, but for some reason my pages return readystate 4 and status 200 prematurely. (These are the codes that say the page is done)
Because this is happening, either the modal dialog is dismissed immediately or I need the user to dismiss it.
Has anyone seen this before? Is this an issue with streaming a file instead of hitting a physical page?
Does anyone have a work-around, or will I need to have the user manually dismiss the dialog?
