I am devloping ASPX pages and I want to prevent caching of pages. So i have used the following code:
<% @OutputCache Location = "None" Duration="1" VaryByParam="none" %>
But this code is working only for the desktop browsers. This is not working in mobile browsers.
I am wanting to design a web application (ASP.NET with vs 2010 and the 4 framework) that should work on mobile devices web browsers as well. Do I have to write 2 seperate web UI's or can I write 1, that is styled differently for desktop browsing vs mobile browsing? I am new to trying to develope for a mobile device, and a push in the right direction would be a big help. I have googled but must not be using the right terms as what I get is not very good.

How to prevent browser from caching image, Trsponse.Cache.NoStore didn't work
since asp.net contains multiple threads that are executing at the same time.so if 2 threads access an object (simple or complex) that i got from the the asp.net httpcontext Cache.can't this lead to state problems on that object if these 2 theads tried to modify/read it at the same time?so what kind of precautions should i implement?for example i am thinking maybe locking the object while working with it? (wont this cause performance problems?)or maybe when i retrieve some object from the cache i should create a copy from it?
or maybe i dont need to worry about this issue at all?

View 1 Replieswanted to know what is the easiest way to interface a mobile phone device with an online system. I have literally NO knowledge in this domain. However, I am brainstorming on possibility of an online application that will allow me to backup my data in nokia set 3110 such as my Address book in the application and restore it. This I want to achieve without connecting my phone to any PC. I am thinking on some way to achieve this by leveraging mobile phone line only. I beleive it may require my application to connect to mobile phone through mobile phone network. Currently my mobile phone line subscriber is offering Address Book backup/ restore service with some charge. I want to see if I can replicate similar features. I would really appreciate if you can give a direction to my random thoughts.If anything is not clear then please feel free to inquire. I look forward to your kind response.

View 2 RepliesI 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?
I 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.
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.
