View 3 RepliesC# - How To Implement VaryByCustom Caching
Mar 15, 2011I'm trying to implement functionality to cache certain pages depending on the host. This is because I can have multiple versions of a page which have the same parameters, and where the only difference in terms of a request is the host that is being requested. So, for example these two URLs will request the same page, but they are styled differently:[URL]and [URL]
I'm going through the example outlined here:[URL]but it's not making sense to me.
I've added this to my global.asax:
public override string GetVaryByCustomString(HttpContext context, string arg)
{
if (arg == "host")
{
return "host=" + context.Request.Url.Host;
}
return base.GetVaryByCustomString(context, arg);
}
and the example states "To set the custom string programmatically, call the SetVaryByCustom method and pass it the custom string to use", with code similar to the following:
Response.Cache.SetVaryByCustom("host");
The problem is I'm not sure what to do with this. I've added the previous line to MvcApplication_EndRequest because it seems like it makes sense, but I don't think this is right because when I set breakpoints in GetVaryByCustomString they never get hit.

C# - How To Implement Caching Of Static Files
Mar 15, 2011I use a Masterpage (asp.net webforms) on my site and I woluld like to implement caching of some static files, like javascript, css etc.
I've tried adding the following to my page_load (in the masterpage) but when I use Fiddler the static files are still under "no-cache".
protected void Page_Load(object sender, EventArgs e)
{
// Set cache for 1 hour on all computers and servers.
// ... Proxies, browsers, and your server will cache it.
Response.Cache.SetCacheability(HttpCacheability.Public);
Response.Cache.SetMaxAge(new TimeSpan(1, 0, 0));
}
What am i doing wrong here?

View 2 RepliesMVC :: How To Implement Page Caching On A Social Networking Web App
Jul 14, 2010i 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.

Jan 27, 2011I am using System.Web.Caching.Cache in an assembly used by my website.
I have set some key expiration (absolute expiration) to be 10 seconds (just for debugging).
I have also set a callback upon key removal.
The problem is that I see that the cache is getting refreshed after something like 20 seconds and not 10.
I am using HttpRuntime.Cache for this.
I would like to show a code sample, which can shed more light:

Caching Css And .js Files?
Dec 5, 2010I want to use caching technique for .js,.css and images( to avoid round trips and to improve performance of page load) .So, on IIS 7 using Http Response Header, i set Content Expriation to 7 days.Now, on browser its caching which is avoiding round trips for static content ...which is good sign.Now, i modified one of the .js file and i deployed that .js file on server and due to caching my new code is not reflecting on client machines .So i tried lot of ways and here is what i tried after deployment of new .js file After deployment of new .js file
1) I manually delete all the browser cache(cookies,urls,forms,page content etc) on internet explorer
2) used ctrl + f5 to get refresh
3) again on IIS i went back Http Response Header section and set Content Expriation to never
4) stopped the website and restarted
5) on web.config file tried this only
<staticContent>
<clientCache cacheControlMode="DisableCache" />
</staticContent>
6) Also tried to set this on .aspx page
<HTML>
<HEAD>
<TITLE>---</TITLE>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
</HEAD>
<BODY>
7) tried to set this on .aspx.cs file
<% Response.CacheControl = "no-cache" %>>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.Expires = -1 %>
My target browser is IE.None of them worked,Finally i renamed my .js file to different file name and changed code to make use of that new .js file ..but no luck on this too .Because what i set intially for 7 days still my client machine remembers that.
How do i tell IIS server to refresh cached content code , when some thing got changde on .js or .cssfiles?
Caching With Javascript And Asp
Mar 15, 2010I asked a question a while back on here regarding caching data for a calendar/scheduling web app, and got some good responses. However, I have now decided to change my approach and stat caching the data in javascript. I am directly caching the HTML for each day's column in the calendar grid inside the $('body').data() object, which gives very fast page load times (almost unnoticable). However, problems start to arise when the user requests data that is not yet in the cache. This data is created by the server using an ajax call, so it's asynchronous, and takes about 0.2s per week's data.
My current approach is simply to block for 0.5s when the user requests information from the server, and cache 4 weeks either side in the inital page load (and 1 extra week per page change request), however I doubt this is the optimal method. how to improve the situation? To summarise:
Each week takes 0.2s to retrieve from the server asynchronously. Performance must be as close to real-time as possible. (however the data is not needed to be fully real-time: most appointments are added by the user and so we can re-cache after this) Currently 4 weeks are cached on either side of the inial week loaded: this is not enough. to cache 1 year takes ~ 21s, this is too slow for an initial load.
MVC :: Is The Page Caching?
Aug 20, 2010I 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.
.net - Out Of Process Caching?
Mar 19, 2011I have a .NET website which queries the DB using Entity Framework every 3 seconds for the status of the transaction using AJAX and updates the page. This status is set by an external client using a RESTful webservice hosted on another server. I want to avoid hitting the DB every 3 seconds for each transaction so want this information cached in memory. The REST webservice updates the cache and website reads from it. Is there any FOSS or commercial Out of Process Shared Cache library that I can use to speed up the performance?
View 3 RepliesC# - Caching, What Would Be A Best Practice
Aug 13, 2010I have a table that stores songs and plays counter.
Here's the code:
//Increse plays counter
string ip = Request.UserHostAddress;
if (!string.IsNullOrEmpty(ip))
{
if (Cache["plays:" + trackID + ":" + ip] == null)
{
tracks.IncreasePlaysCounter(trackID);
Cache["plays:" + trackID + ":" + ip] = true;

}
I wonder what would be a better practice, store many cache items(like this) or store one item like a ArrayList that would contain the users who already heard that song. Is there any difference?

View 1 RepliesC# Data Caching And How To Invalidate
Mar 17, 2011My web application is using the asp.net cache object to store data from the database. I am looking for an elegant to invalidate cache objects but haven't come up with anything elegant yet. It is easy to invalidate a single record or a list of all records in a single table, by keeping track of their cache keys. However I may have any number of lists of subsets of a table's data. I would like to invalidate only the cache records of the lists that contain a particular record, when that record changes. I don't want to have to invalidate all the lists of data for that table if only one of the lists contain that record.
View 1 RepliesC# - Image Caching In Application Without IIS?
Dec 6, 2010I have an application written in asp.net c# and hosted on IIS6. There are an 'Image' folder with 3-subfolders. These folders contained images of type 'jpg','gif','png' etc. Images are very huge in size and in numbers. On the application every page has some images needs to open/show, due to the size of images my application get slower and slower.
I know there are some techniques to Cache image folders at client machine or some other methods. I have no access on IIS. So, I need some httphandler or httpmodules which provide something like Image-caching.
I tried this : codeproject.com/KB/aspnet/CachingImagesInASPNET.aspx The problem is I have to add an extra extension '.ashx' to every image link. There is no problem with images are loading dynamically but it has trouble with images need to embose a manual link. Also, this is working fine upto around 1000s images.
