Web Development - How To Share Application Cache Between Two Applications
Oct 27, 2010
I have one website over at utopiapimp.com. The website is used for a popular web based game. Some company internets don't allow the website to be accessed so I opened up another domain at utopiashrimp.com. Same website but a different iss application. Both have same database backends. They also both sit on the same virtual machine. I put my brand new code on shrimp and solve bugs with that code. I host the solid code on pimp. So I can't just forward the shrimp domain to pimp because I need a test bed.
The problem is that they don't share the same application cache. So my question is, can two websites share the same application cache? I really need to figure this out. I would rather not create a webservice and or a handler that one website needs to hit to change the cache on the other application.
I have a solution with more than one ASP.NET web-application. Every application has its own virtual directory on the same IIS. One application is calling aspx pages in the other applications. How can I share some information (e.g. user/password) between these applications. Is the only way using querystrings (in this case, I must encrypt the information).
/Web --this is the client facing site /Web/Admin --this is the backend system and is setup as a Virtual Application
I'm using HttpRuntime.Cache for caching calls to the database. What I want to be able to do is clear something that is cached on the /Web site from the /Web/Admin site. It appears though that HttpRuntime.Cache is a single instance per application.
I would like to create a web application that gives an overview of all latests builds of a Team Foundation Server (TFS). The original idea was to simply query the TFS for all these builds and display the results using html. Now the problem is that this is just too slow. It takes around a minute to get the required informtion. I can't inluence this, it is just given. So I came up with the idea of caching. I could cache all results for a certain period of time and then invalidate the cache but as soon as the cache expires someone that uses the application will have to wait again which is not that nice.
The Team Foundation Server is able to notify whenever a new build is available. So basically the idea is that the application could react on that notification. In order to be notified I have to write a web service and register it with the TFS. That worked pretty well so far. The web service is now notified whenever a new build is done. Now I would like to connect my web application to the web service and whenever the web service is notified by the TFS update the cache of the web application. Here starts the problem. How can this be achieved? First I thought that the web service could fire a .NET event and the web application could react on that event but that does not seem to be possible. The next idea was that both the web service and the web application could use the same cache. The web service could then directly update the cache with the build information it receives from the Team Foundation Server but I am not even sure if this works.
Can a web service and a web application share the same cache? The web service doing something like Cache.Add("key", buildInfo) and the web application buildInfo = Cache["key"]. If not what other approach could be used to solve such a scenario?
im about to wirte an app that is an extension from the main application that is hosted on the IIS. My application is going to work as a child app (main app as parent) working in main application pool. User will be redirected from the menu to main app to my website. And here is my problem. I would like to pass informations like user login, login state etc. I cant do it via Query String - that wouldnt be safe. I thought I could pass it via Session state, since the SessionID is the same both sides but I cannot retrives parameters on my website(theyre null).
Is there a way that I can share membership (login, etc.) between two different web applications? I would like to create a smaller debug application to test some stuff in my database.
I recall some way to use a single instance of the the asp.net membership for multiple applications. For example...if I have a main single sign on portal, perhaps I'd like them to have access to Application A, B and F, but not C, D & E. Instead of maintaining different security for each application, can we have a single membership table maintaining all of the enterprise applications? So user 'John Doe' would have a single membership record, but have access to different applications.
I'm looking into building a web application platform which users will log into and be able to access other applications based on permissions. I've set up the membership provider and it is being shared between apps. Here is my problem: If I log into application A, and click on a link that takes me to application B, I have to log in again. Is there any way to share that session between applications so the user can log in once, and not have to do it every time they access a different application?
I have a bunch of applications that currently share the authentication cookie in v3.5.
We're in the process of upgrading to 4.0 and also upgrading the applications as a whole. I have 1 done, and would love to deploy it. However, as soon as I do, I lose my sharing of authentication cookie in that application.
In each web.config, my machine key is declared. I removed the actual keys to protect the innocent. :)
<machineKey validationKey="..." decryptionKey="..." validation="SHA1"/> <authentication mode="Forms"> <!-- DEV Server --> <forms enableCrossAppRedirects="true" loginUrl="Logon.aspx" name=".COOKIENAMEHERE" protection="All" path="/" slidingExpiration="true" timeout="1440"/> </authentication>
I am trying to integrate an existing asp.net application with sharepoint 2010. I would like to be able to have a logged in user on the application access a document library via an Iframe on the sharepoint 2010 site. I want to use FBA on sharepoint. Is it possible to share the membership database from the asp.net application with sharepoint? If not, what would be the best way to accomplish this?
Is it possible to share the claims based authentication of a logged in Sharepoint 2010 user with a separate Asp.net application?
The following article describes how it was done using Sharepoint 2007 and forms authentication through forms auth and sharing machine keys etc however I cannot find any information regarding the external application consuming the claims authentication that is now used in Sharepoint 2010?
We are developing a framework which will be shared accross applications. What is the best way to share master pages, user controls accross applications by preventing other developers to modify the master pages and the user controls ?
Is the following way suitable one ? Embedding masterpages and the user controls in a dll and using VirtualPathProvider to load the master pages and user controls dynamically.
But in this approach developers can not view the design. Is there any other way to convert master pages and user controls to a different format as developers can able to view design?
We have a web application that is storiing all site data in HttpRuntime.Cache. We now need to deploy the application across 2 load balanced web servers. This being the case, each web server will have its own cache, which is not ideal because if a user requests data from webserver1 it will be cached, but there next request might go to webserver2, and the data that their previous request cached won't be available. Is it possible to use a shared-cache provider to share the HttpRuntime.Cache between the two web servers or to replecate the cache between them, so that the same cache will be available on both web servers?
I need to invalidate cache in a web application when related data is updated in another application (running on the same machine). Both applications use the same database. I know there's SqlCacheDependency. How do is it in terms of performance? Is interprocess communication (e.g. using name pipes) an option in web applications? Does it outperform SqlCacheDependency?
I need to develop an interface so that from that User can access different applications and give the credentials and display the only some important data of that site.how to achieve it .
i want to know how do i deploy ASP.NET web applications on client machines which runs with the visual studio development server rather than configure it in the IIS on the client machine? I know its possible and telerik also uses this approach.
I recently received a project that contains multiple web applications with no MVC structure. For starters I've created a library (DLL) that will contain the main Business Logic. The problem is with Caching - If I use the current web context cache object than I might end up with duplicate caching (as the web context will be different for every application).
I'm currently thinking about implementing a simple caching mechanism with a singleton pattern that will allow the different web sites (aka different application domains) to share their "caching wisdom". I'd like to know what is the best way to solve this problem.
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).
Im building a image gallery which reads file from disk, create thumbnails on the fly and present them to the user. This works good, except the processing takes a bit time.
I then decided to cache the processed images using the ASP .NET Application Cache. When a image is processed I add the byte[] stream to the cache. As far as I know this is beeing saved into the system memory. And this is working perfect, the loading of the page is much faster.
My question is if there are thousands of images which gets cached in the Application Cache, will that affect the server performance in any way?
I have some common dlls that are referenced by both a windows service application and a asp.net web application. I don't want to make separate copies of the dlls and I also don't want to put those dlls into GAC. I try to put that service application under the same root folder as the web application so that they can share the same bin folder. I am not quite sure if this will cause any problems? I did find the web application had random session timeout, but not very often. Not sure if it was caused by the shared dlls.
I have a web.config file defined in my asp.net web application. I have many different settings configured there. I have another project, this time a console application. I'd like to read several configurations from my web.config file. How can this be done?
My company took some old php application over. Due to our preference to ASP.net and to the lack of any documentation from the previous developer, we do not want to spend much resources on developing in PHP. For implementing new features, we will create an Asp.net application that has the same look to the user. We want to develop a kind of 'coexisting' web application. Therefore we must share sessions between an PHP and an Asp.net webapplication project, because there is a usermanagement involved with an existing MySQL database.
(e.g. link 'A' directs to the PHP website, and link 'B' directs to the asp.net application)
How can we share the session between and PHP and an asp.net application?
And does anyone have a hint for this 'coexisting' thing, that might be useful in development?
I have two urls that are supposed to lead to the same actual folder.
I can't do a redirect because the websites are built so they question the URL and perform accordingly.
So I built two application in the IIS (I tried using a virtual directory for one of them, but I kept crashing on the web.config can not be read). Everything works perfectly except the Application variables which are different between the two addresses. (Specificly I'm counting the number of current users logged on).
In this asp.net web application, users can upload files to the server through a web interface. All the uploaded files are save in a server side folder. If I want to create a new win form desktop client (actually, its a WPF application) which can be used to upload files to that same server side folder as web interface does, how can I share that server side folder with that win form client?
