MVC :: Is The Page Caching?
Aug 20, 2010
I am just trying to understand the basics flow to the MVC framework by putting in some breakpoints in the beginning of the actions of a couple of controllers.
One break point is at the HomeController/Index action where it just returns View() of the "Welcome to MVC". The Second break point is at a SecondController/Index action where it uses the Entity Framework and returns a View() of a list from the db.
When I run this in debug, it breaks at the points I expected when I go from Home page to the Second page controller and back to Home. However, when I go to the Second page again, it doesn't break at all? Is the results of the Second page being cached and how and where? How do you trigger for it to get check if data is old?
I check to see if the persistence is done on the db, by changing the value of a field on the db side and it still did not cause it to break on that action and displays old information in the view. I am concerned because it is displaying incorrect values on the UI. I do not have the OutputCache attribute above this action or specified any cache on my web.config.

I have a page with a number of user controls, In one of my user controls I have a button event. I turn on output cache for the user control that has the button and vary by control using the ID property of a hidden field control in the user control. whenever I turn on the output cache my button event doesn't fire.

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.

I'd like to pass data from one asp.net page to another. I've seen that using System.Web.Caching.Cache is a good way to accomplish this. I'm wondering if it's a good way to do it and also is there any cleanup or other things I need to keep in mind when you the Cache?
I'm not passing very much, at most two integers.

I have a admin page in asp.net that adds data to a database. This database is available as a JSON string to external websites, however, since it's a lot of data, the external websites cache this data locally.I want to be able to ping the external websites to let them know the data has changed so they can referesh their cache. I figure I can setup an ASHX handler that receives a parameter telling them what data has changed, so they can both delete that data and refresh it.The only part I'm not sure about is the best way to call this external page from my admin page. Do I just do a regular WebRequest and discard the result? or is there a simpler way to call a page from code when you don't need the response?

We have a small web farm(2 servers) balanced by the built in network load balancer in Windows 2003. We have a few pages that use page caching. My question is: Is it possible that that a given user could cause a page to be cached and another user see that content? Here is the page directive for the page in question:
<%@ OutputCache Duration="1" NoStore="true" VaryByParam="none" %>
The reason the duration is set to "1" is to ensure that the page isn't cached any longer than 1 second because of transactions that actions on the page can trigger.

I have checked this thread. [URL]
And wondering if I can put the answer inside page_load ?
If not how do I disable the cache on for a single page?

[OutputCache (Duration=20, VaryByParam="None" )]
public ActionResult display()
{}
This code cache whole page.But, my site has user infomation on top like this ASP.net. The user info "Signed as userid | Edit Profile | ..." section should be changed when user sign in/out. But rest of the page is always same and it's good to Cache.
If the above code is used, the user info on top also cached and give wrong info to user.

If I set cache on an ASP.NET page and have content, a control, in the master page then is that cached, as well?

I have an aspx page that retrieves and processes an image based on a query string.The whole operation takes about 2-3 seconds. However as the nature of the images means they are quite static,a 5 min (or even 5 hour) delay in picking up an updated image is acceptable. Because of this delay I would like to cache the response and only do a proper refresh only periodically. I have added the following to the top of my aspx page. <%@ OutputCache Location="Any" Duration="600" VaryByParam="*" %> Only the last request appears to be cached - i.e. f I navigate to ../DisplayImage?ImageId=1Then the page is loaded and Image 1 displayed - subsequent requests are cached.If I navigate to ../DisplayImage?ImageId=2 subsequent requests are cached. However if I go image 1, image 2, image 1 then no caching occurs.
I'm wondering if i'm missing something obvious or does IIS7 / ASP.NET just not support this type of caching.

I've seen a number of options for adding GZIP/DEFLATE compression to ASP.Net MVC output, but they all seem to apply the compression on-the-fly.. thus do not take advange of caching the compressed content.
Any solutions for enabling caching of the compressed page output? Preferably in the code, so that the MVC code can check if the page has changed, and ship out the precompressed cached content if not.
This question really could apply to regular asp.net as well.

i am in the process of developing a social networking web app using asp.net mvc 2 and asp.net 3.5 sp1.I have implemented user authentication and role management (like admins, etc...) and i was wondering how i could implement page caching in such a scenario based on the user currently logged in.
Note that the web app page urls may, or may not contain the name of the user authenticated and that there are also pages available to both authenticated and both authenticated users.
What i would like to avoid is to make a cache version of a page for an authenticated user, available to a non authenticated or to another authenticated user.

We use Page.ParseControl to interpret a string of XML into controls. Does it use some kind of caching mechanism? If not - is there a way to cache its result?
Page.LoadControl seems to support some sort of caching.

I have a page which contains a user control. The structure of the page is as shown below:
Incase your not able to see the above image, check it at [URL] Now, apart from the contents of the UserControl, I'd like to cache the entire page. I tried using the OutputCache attribute in the .aspx page, however it caches the contents of the UserControl as well.

I know that when declaring a page method in ASP.NET, I can specify a CacheDuration like so:
[WebMethod(CacheDuration=60)]
public static void Foo()
{
But from what I understand, CacheDuration only supports absolute expiration. I want to have sliding expiration. So that leads me to believe that I need to access the System.Web.Caching.Cache object somehow. But, since page methods are static, and this is essentially a standalone web service, I'm not sure how to access it statically. The only ways I have seen on Google rely on getting it from the HttpContext. But, there is no HttpContext available to me here, right?Or, do I need to use the System.Runtime.Caching.MemoryCache to do my own caching?

How do I implement partial page caching with an AdRotator control? I know it's supposed to do it automatically, but I'm using the AdCreated event to handle stats, and this seems to cause the ad to be cached along with the rest of the page.

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();
}
