State Management :: Sharing Cache Between Two Web Applications In The Same Solution
Jul 7, 2010
I have an asp.net solution in which there are two web application projects (client website and admin website) and also a class liabrary project in the same solution . In the live production server, the admin web app is within the client app (eg: client site= [URL] and admin site=[URL]). A class (with static variables) in class liabrary is userd to cache data. My problem is that i cannot get the changes to the static cache by one web project reflected to the other (becoz, i think, they seem to load in seperate appdomains).
I would like to share the session variables between 2 applications. basically I have a website and in there I have 2 applications and want to share the session object betwen the two. Is there a way to set something in web.config to enable this?
I have 2 applications App1 and App2 on same domain, both with Forms authentication, each using a different database instance for authentication.
First, I open a browser with application www.mydomain.com/App1 and log on.
After that, when I open another instance of the same browser with application www.mydomain.com/App2 and log on, first browser loses session and goes back to login page.
I need each application on same domain to have its own session so that both can stay logged on.
I have two different IIS applications within the same domain(let us say www.mydomain.com) , both of these applications use the same database instance(same connectionstring), now what I want is that both of applications can see each sessions variables , can SQL Server session state mode helps in this case? Did someone try that before? Is there any other way to share the session variables?
In my website I am maintaining cookies for the login so that if I open the browser again then no need to login again.
But when I am switching browser(from ie to ff or viceversa) then the cookies are lost and the user is not identified, I want to maintain them in this scenario also.
I have a website A which has a link to website B which is currently opening in a different window. When clicked on a link to, the login for B is automatically taken care of as both the websites have same user login credentials.
Now a change in the system has made me embed website B into website A. ie., B will open in the same window of A.. I could achieve this using an IFrame. Now, the session from site A needs to be carried out to site B. Presently, when navigated from A to B, all the sessions on A expire. Once navigated to B the session time out of B from the webconfig is taken. I have used "InProc" as my state management option in web config. Is it possible to maintain single session for both the webistes? If not how to continue same session times for both webistes? I do not want to use "SQL server" state mode.
how do i pass data between two asp.net webservice sessions ?
this is the scenario, we've windows application and web service. our windows app calls a third party web site which requires data from our applciation. this 3rd party suggested that we create a web service that they can call from the web site.
after some reading it looks like i can use "application" object to store the data so that we store data in session with a specific session key and give it to web site and web site passes this session key in all methods it uses in webservice. is this best approach to take ?
After doing some research, I found that <sessionState> can be hosted in SQL Server allowing applications to read from the same source. Essentially my app has two sides: a WCF library and an ASP.NET MVC 3 web site, the WCF has authentication and other DB IO methods and the MVC does the display. Now, the MVC stores a value in the session and then the WCF reads it and creates another for the MVC to read later. Problem is, neither can read each others session data, they can write to the same repository but can't share.
How do I go about them sharing the same information? How can I tell <sessionState> that the session started on the MVC side is the same as the WCF side and viceversa? I've tried
i have two solutions, 1. user management and 2. travel management. i publish the user management solution to [URL] and i publish the travel management to [URL] here i face the problem. the default home page would be [URL], its a windows authentication in page load, i capture the username, pass it to procedure which will fetch me his credentials on access. i store these in a session.
in the home page i have link to navigate to travel page, when i try to access the sessions in travel page, its empty. i tried printing the session id in both user management and travel, both are same but the sessions created in user management are empty in travel. what would be problem here and how can i resolve this.
If I want to share cookies among applications, applications need to be in the same domain. In production it is no problem. But I have problem with development. If I run those applications in Visual Studio, it runs application in "localhost" and it is not same domain. I don`t see cookies among applications.
I have 2 different applications hosted on an IIS server. I have created a new application pool.Can i run both the applications on the same pool??Will sessions or other values of one application be available to the other application if I do it this way?
i have two applications hosted on two different domains and both use a single login info so my question is how can i use / share same session across two application.
I have some weird problem. We're using Windows Server 2008 R2 x64 (8 Cores and 8 GB RAM) with IIS 7.5 and ASP.NET MVC 2.
I always cache (simple) stuff via the context cache and it seems like 9 out of 10 immediate page refreshs the Cache["MyKey"] is always null, even though there's no memory limit set on the pool and the server has lots of free memory.
I add expiring data via:
[Code]....
When just doing: Cache.Insert("MyKey", myObject); or Cache["MyKey"] = myObject; I get the same result (cache is almost always null for that key).
As you can see I added a callback, which writes the CacheItemRemovedReason to a text file, and the text file says CacheItemRemovedReason.Removed for MyKey. The doc for CacheItemRemovedReason.Removed says, that I call Remove/Insert on it, even though in my whole project there's no "Remove"-calls, just simple if(Cache["MyKey"] == null) {Cache["MyKey"] = ...} stuff.
I have a treeview that shown groups and their sub groups in my usercontrol. I pass the parent GroupId to the usercpntrol from the page. I want to cache nodes of treeview for every Parent Group Id. My code is works good for first time and fill the cache object . after refresh the page, cache object fill the TreeNodeCollection succesfully and everything is ok. But after another refresh, cache object is not null but is empty and TreeNodeCollection.count is zero(0). What's my fault? Please help me to solve this problem.
I am looking for an elegant (i guess as elegant as it can be) solution to caching a users profile on login (whether it is session, cache, cookie, etc) and keeping it in sync when a users profile is changed. How do you guys handle this? Just simply call a Flush() method in your Save() method that invalidates the cache?
I'm trying to cache a complex page with lots of controls on it so that if the user navigates to it later it will look like it did when he last saw it.The page has controls which post back and other controls are populated depending on the selections.
I'm using [Code].... after the <@ Page directive.
What happens is that a postback gets the cached page, so no processing and it looks the same regardless of user selections. So far so good. But if I browse to another page and return by a link, the cached version is ignored and the default page is created again. This is more or less the opposite to what i want.
I attempted to use the validation callback to ensure that a postback resulted in a new version, and that worked, but it still ignored the cached page if it wasn't a postback.I realise that it will need more work to ensure each user gets their version of the page from the cache, but why bother if this doesn't work.
I know the big difference, but one thing is confusing me. Cache works only on a single machine on webfarm and to make it globally we use Velocity or memcache.So is static does same, or is it already work globally ? eg
Cache["someid"] = "value"; //this will only work on single machine cache,
static string abc = "value"; // will this work on single machine or globally ?
I wanted to know the best practice for caching data. Say I have some control example a dropdown list which is populated from my db. Now this dropdown is global and used across many pages. I was thinking of not going to database everytime to fetch data for this dropdown and put the result in Cache. And then populate this dropdown from cache. Is this a good practice or if there is another approach. Can I store my datareader in cache and then use it globally. Also could I do this in application start event?
