Prevent Page From Being Cached When Using OutputCacheAttribute?
Nov 9, 2010
Is there a way to prevent a page from being cached based on some logic?
I want to cache anonymous access to a page, so I can set VaryByCustom="user" and have some magic in Global.asax's GetVaryByCustomString method. Ok. But I don't actually want to cache the page if the user's authenticated, only if it's not authenticated. Is there a way to specify this kind of thing?
The reason I want the data to not be added to the cache to begin with (instead of added with some random key) is that as the cache grows things get thrown out and I don't want the non-authenticated version to get thrown out.

I would like to ask if there is a way to prevent Firefox from caching scripts (.js files).
I have a project (ASP.Net Web App) with caching issue on firefox. When I first run the application (script is being cached on firefox) and modify the script and rerun the application, firefox is using the cached script instead of the updated one.
I'm using Firefox 3.6.13.
I already tried using HttpHeaders but it seems like firefox is ignoring my codes.
Here is my code:
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Cache.SetAllowResponseInBrowserHistory(false);
HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
HttpContext.Current.Response.Cache.SetNoStore();
I tried placing this code at global.asax > Application_BeginRequest and at MasterPage.aspx.cs > Page_Load, but it isn't working.

I have an input field on a webpage that contains a credit-card number. What is the best way of preventing the browser from caching this value?
Any solution needs to work on a large selection of browsers.

In my ASP.NET app, I noticed that the results of any web service calls are cached. I don't want any results to be cached, how can I stop the browser from caching the results?Update:Here's the proxy code generated by calling the web service URL appending '/js', e.g. /mywebservice.asmx/js
var MyWebService=function() {
MyWebService.initializeBase(this);
this._timeout = 0;
this._userContext = null;
this._succeeded = null;
this._failed = null;

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.

why all the resources in my page are being requested EVERY single time. E.g. my site.css returns the following headers (using fiddler):
HTTP/1.1 200 OK
Server: ASP.NET Development Server/9.0.0.0
Date: Mon, 29 Nov 2010 17:36:21 GMT
X-AspNet-Version: 2.0.50727
Content-Length: 9093
Cache-Control: public, max-age=2592000
Expires: Wed, 29 Dec 2010 17:36:21 GMT
Last-Modified: Mon, 08 Nov 2010 17:20:16 GMT
Content-Type: text/css
Connection: Close
But every time I hit refresh I see all the resources (css,js,images) getting re-requested. I have control over the headers returned for any and all of these resources, but I haven't figured it out yet.I have even debugged my ASP.NET app and the HttpModule is definitely being asked for the resources again.
EDIT:Ok, I removed must-revalidate, proxy-revalidate from the headers and that is getting me closer to where I want to be, now when I press back it still requests my css/js files when I press back.

Is it possible to detect whether an ASP.NET Page is about to be cached and if so, how?The HttpCachePolicy object provides only set-methods. The VaryByParams name-value collection is useless if values other than "None" and "*" are set as it impossible to enumerate them and you can only access them by key

My web page is still displaying a previously cached versions of the page. I have this in the page_load event:
Response.Clear();
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
Response.Expires = -1;
Response.CacheControl = "no-cache";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
I have this in the Page_Init:
protected void Page_Init(object Sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddDays(-1));
}

Lets say you have a page with headers that tell the browser not to cache.Also, this page has already been posted back to itself.Now you hit the refresh button and you click cancel on the IE modal box with the "previously submitted..." message.You get "Webpage has expired". This doesn't happen in FF or Chrome.Is there a way to prevent the "Webpage has expired" message in IE?Since the page isn't cached, I guess IE has nothing to render.But if the page isn't cached and FF and Chrome shows it, I guess they just show the page as previously shown?

I Have a TreeView that I populate from a DataTable.Once it has been populated, I Cache the Treeview.If I try to add the cached TreeView control to my page, nothing happens. No errors no nothing.If I create an empty TreeView control on the page and do a "Do Until" loop and add each node to that empty TreeView, that works! but only once. The next time it loops, for some reasion the CachedTree.Nodes.Count = 0.I can't see what I'm doing wrong.

I'm pretty new to ASP.NET and very new to the concept of caching.
Using MCMS 2002, I built a template.aspx page that receives a "person_id" query string and builds pages accordingly. Several different departments at the school where I work are using this template to display faculty biographies. This much is all working correctly.
The Problem
The problems start happening when I try caching the page. When a person visits person_id=16175 on one department's page, then visits the same numeric bio on a different department page, it loads the cached page instead of rebuilding it. The problem, then, is that it has all of the wrong department branding. For example:
[URL]
It's the same person_id, but the URLs are obviously different. It would be great if the template would recognize the different URLs and ignore the cache. I'm assuming that the problem lies in the fact that both pages are being built using the same aspx page on the backend. Here's the OutputCache bit from the aspx page:
<%@ OutputCache Duration="86400" Location="Server" VaryByParam="person_id; section" VaryByCustom="CMSPosting" VaryByHeader="Referer" %>
I assume I'm doing something wrong here. Hopefully it will be obvious to someone who knows that they're doing. If you need more info, don't hesitate to ask.

I am a problem with Postback event.
I have a web page (aspx) which takes longer time to load the page. If this page is loading and if user requests same page by clicking menu link again, it is considered as not postback and page starts loading again (as soon as it finished first page load).
I want to prevent this from happening. When page is loading and user requests same page again, it should not process those requests and should be neglected.
This aspx page is requested from menu (which is designed on seperate master page).

I have an Ajax form with a single input and a button. On submit, the form should only post the entered value to an action method. My form is correctly posting to the User controller's Log method but when done, the page redirects to /User/Log.
How can I avoid this?
