Web Forms :: Clear Out The Cached WebSiteMap?

Jul 16, 2010

I am using the SqlSiteMapProvider to build my Sitemap ... but I'm guessing that this question is valid for any type of site map.

There's a very specific instance where I need to rebuild the sitemap because the user completes a task and I need the Sitemap to rebuild to reflect that. I don't want to get rid of the natural caching that comes with the Sitemap stuff so I'm wondering if there's some way I can clear the cached map just when this certain task gets completed.

Is there some [Sitemap].clear() type method I can run for this?

Modify An Object From Cache And It Changes The Cached Value

May 8, 2010

I'm having an issue when using the Asp.Net Cache functionality. I add an object to the Cache then at another time I get that object from the Cache, modify one of it's properties then save the changes to the database.

But, the next time I get the object from Cache it contains the changed values. So, when I modify the object it modifies the version which is contained in cache even though I haven't updated it in the Cache specifically. Does anyone know how I can get an object from the Cache which doesn't reference the cached version?i.e.

Step 1:
Item item = new Item();
item.Title = "Test";
Cache.Insert("Test", item, null, DateTime.Now.AddHours(1), System.Web.Caching.Cache.NoSlidingExpiration);

Step 2:
Item item = (Item)Cache.Get("test");
item.Title = "Test 1";

Step 3:
Item item = (Item)Cache.Get("test");
if(item.Title == "Test 1"){
Response.Write("Object has been changed in the Cache.");
}

I realise that with the above example it would make sense that any changes to the item get reflected in cache but my situation is a bit more complicated and I definitely don't want this to happen.

C# - How To Invalidate Cache When The File Which Is Cached Changes

Dec 17, 2010

I read few xml files from a location and cache them using Http context cache. Anytime the xml files changes i have to do a IISReset to view the latest changes.

I use this

System.Web.HttpContext.Current.Cache

I have to use the caching as i don't want to read all the xml files all the time. i read it once and caches them for a day. They get reset whenever apppool recyles or anyone manualy do a IISReset.

Is there anyway in asp.net to invalidate the cache if someones changes the xml file.

Add Or Update Or Delete Cached Data - Remove The Entire List From The Cache

Jan 17, 2010

U are caching a list of items, then Add or update or delete method called. Approach 1)

A- Do the data change at the database. If success do B, C
B- Remove the entire list from the Cache.
C- Re-Cache the list on first read.

Approach 2)

A- Do the data change at the database, If success do B
B- Do the same change at the cached items, and save more time.

Approach(2) probably will cause nasty difficult to spot bugs, because the data come from BLL and placed directly into cache, One can't assume no bugs will happen at the sproc, I am not worry about database runtime errors, runtime errors will show up, but I am worry about invalid data, or miss calculation. Can I proceed with approach (2) with caution? Is there a "best practice" principle which suggest not doing approach(2)?

Web Forms :: Clear Cache On User Control With Vary By Id Parameter

Aug 1, 2010

I have a page that deploys a user control to display an article. The page will show a different article depending on the ID parameter fed in via querystring, and there are many thousands of articles in our db. Here is the problem: I need to cache the user control to improve performance. But editors constantly need to go in and make changes/corrections, which they want to appear instantly on the site. Is it possible to clear the cache for a specific article only once it has been edited? ie for the request article.aspx?id=123? If so how would I do this? Otherwise, if the cache is cleared for all our content every time a single piece of content is edited, it will defeat the object of caching in the first place. I have tried using a cache key as recommended here: [URL] However, this apporach suffers from the drawback mentioned above. have also seen that you can set caching up to be cleared by changes to the db. However, the particular table concerned holds content for a number of other sites and would also have the same disadvantage.

CSS In App_Theme Folder Gets Cached In Browser?

Dec 23, 2010

The Stylesheet in the App_Theme folder gets cached in the browser. What should be the approach? so that whenever there is a new deployment the browser should take the latest stylesheets and not the one cached in the browser.

This was happening for other css(which are not in theme folder) too, so used custom control as mentioned in the link

[URL]

How this could be done for the CSS in the Theme folder?

Edit: The theme name is mentioned in the web.config as mentioned below. so its not just the html link tag which I had solved by using the method mentioned in the link.

<pages styleSheetTheme="Default">
<controls>
</controls>
</pages>

Clear A Cache For A Custom 404 Webpage?

Mar 10, 2010

I created a custom 404 page and set its output cache duration to 7200 seconds (the pages themselves aren't updated more than twice a day, so I figured this was reasonable).

I ran into an error on the live side of things when I uploaded it, and I'm trying to debug and solve it. The problem is that I can't seem to figure out how to get rid of the cache itself, which definitely appears to be getting in the way. The reason I say that relates to my stack trace:

Server Error in '/' Application.

Input string was not in a correct format.

Description:

An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.FormatException: Input string was not in a correct format.

Source Error:

[Code]....

Stack Trace:

[Code]....

I've been trying to debug the ExtractURLComponents sub, and even commented out every line in it.

[Code]....

I'm still getting an error, even with every line of the sub commented out. So this is why I'm thinking it's got something to do with the cache. I tried clearing it with a different page using this:

[Code]....

I'm not sure if there's anything I'm supposed to do to clear the cache.

C# - Clear Client Output Cache On Log Out

Jul 20, 2010

My web client requires client-side output caching since it makes use of its own Back and Forward buttons (which basically just call the browser back/forward buttons).

The issue I'm having, however, is (of course) when the user signs out of the app. The client-side output cache remains so anyone can click the "back" button and it appears to be signed in again. I've researched a few solutions, but most involve server-side output caching or no output caching at all.

I've had success with server caching and HttpResponse.RemoveOutputCacheItem, but unfortunately I need the client side caching.

Is it at all possible to clear this client side output cache upon logging out?

Iis7 - How To Stop Cache

Jun 7, 2010

I'm seeing an issue of some static pages that are using the browser cache, which is not desired. To prevent caching, I'm setting

<clientCache cacheControlMode="DisableCache" />

in the relevant <location> tag in web.config

If I open the page in Firebug (in the Net tab), I see that the Response headers have Cache-Control: no-cache which is correct, but the status of the Response is 304 Not Modified! Isn't that a contradiction? How can I get it to stop caching (i.e. always send a 200 with content)?
