I have a website that i did some time ago now they request some new features and i did some changes in some javascript files, but when i publish the clients that use the IE have problems with cache so in they browser they have old version of javascript. How can i clear the client cache so when they visit website they use latest javascript files that i modify.
View 1 RepliesMy 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?
I have various caches on my compiled website. However, I need to clear all these caches. Is there a way of doing this (without having to restart the server!)?
View 1 RepliesI've built a Repository that gets user details
Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID
Dim user = (From u In dc.Users
Where u.OpenID = openid
Select u).FirstOrDefault
Return user
End Function
And I'd like to be able to pull those details down IF the user is logged in AND IF the cached data is null.
What is the best way to create a User object that contains all of the users details, and persist it across the entire site for the duration of their visit?
I Was trying this in my Global.asax, but I'm not really happy using Session variables. I'd rather have a single object with all the details inside.
Private Sub BaseGlobal_AcquireRequestState(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.AcquireRequestState
If Session("UserName") Is Nothing AndAlso User.Identity.IsAuthenticated Then
Dim repo As UrbanNow.Core.IUserRepository = New UrbanNow.Core.UserRepository
Dim _user As New UrbanNow.Core.User
_user = repo.GetUserByOpenID(User.Identity.Name)
Session("UserName") = _user.UserName()
Session("UserID") = _user.ID
End If
End Sub
My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

View 5 RepliesI work in a multi server , multi webfarm environment (without sessions). We need to be able to identfy if a customer has arrived here for the first or has been before (even though they have not logged in)Not only will we change the text of our salutations depeding on this state but we will also use it in other busness logic. I can check for the existance of a cookie when they fire the Session_onStart event but I would have to write a cookie out to show they had previously visited for the next time the customer came to call.
If I wrote the cookie out in the Session_onStart then somehow I would have to tell the website that this was a first time visit. Also as this is a stateless webfarm - the next server may be different from the previous one which would fire a new Session_onStart event in its own right - which would see the cookie and assume it was not my first visit, even though it was my first visit on a different web page of the web site.
I dont want to write it out and say if its within X minutes of the cookie creation time you are still in your first visit as that x minutes wouldnt work 100% of the time If I dont write the cookie out on Session_onStart then when could I write it out?
I have a problem i want to check when prospect visit the website and see what page they link at in c#.

I have an app which I distribute to several people. Now, If one person who runs the app has .NET version 2.0 installed, I must get that info...and if another guy has 3.5 installed, I need that info .I tried with the Environment.version, but that gives the version of the application .
I'm looking for possible ways for sending files from browser to server.
One obvious way is using form with enctype='multipart/form-data'.
I wonder if there are other ways than this.
The reason I ask you this question is this file uploader: http://aspnetajax.componentart.com/control-specific/upload/features/core_features/WebForm1.aspx
It's not flash based, but it sends the file in a way that it gives you a progress bar, but when you send a file with form with enctype='multipart/form-data' the whole file will be send to the server so you can't actually show a progress bar of uploading process.
I have a large scale application which uses javascript for many reasons. these javascript files included in some JS files and JS files imported to Asp.net Masterpage files.
this JS files contents (javascript functions) will add to page when page display to user, so a Bunch of waste Javascript functions will include in Asp.net pages.
I'm lookingfor a way which these JS files downloads to users computer (any where, e.g: temporary internet files or some where else) and the Asp.net page use that functions which downloaded with page.
I also want to download 1 time ( per user login or per Open Session ) to users computer.
So How to download JS file to Users PC and Use them in Asp.net Pages
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.
In my site i m redirecting to login page when i m clicking on loguot button. before that i have written follwing code for clearing cache/history-
Session.Clear();
Session.Abandon();
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
Response.Cache.SetNoStore();
but when i m pasting previous page url in address bar then it is showing that page. i dont want to show that page.
In my aplication (ASP.NET + c# ) when user goes to a aspx page , I need to clear cache first.
Does anyone have any idea how can I progrmaticaly make clear cache on an aspx page, or in it's code behind (c#)?
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.

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.
How do I force a control+F5 (deleting cache) when updating an application? The users will not do this so I need to force this. Can we use some kind of flush method checking version or...?

View 1 RepliesI 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.
