Share Cache Between Web Service And Web Application?
Mar 19, 2010
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?
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 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.
/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.
We have a wfc layer that wraps the business classes and database access and use a client that lives on the database layer. Amongst our group we are attempting to form standards. Some want to have the client call the web method and pass the page they are requesting and the page size. Pass that to the database and then page in SQL Server use RowNum.Some want to cache the full list of objects in http cache on the service tier and page in memory. They concern here is memory use on the server.
Which would be best for a medium number of users with potentially large number of records to manage (say 30K) Is it better to cache them all in memory and work from there or page at the database as the application scales?
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?
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?
Im using asp.net website with WCF service, having wsHttpBinding,Aspnet compatibility enabled, specified as Sessionmode -allowed, service behavior- isinitiated and client session cookie enabled. Its looking like Asp.Net session object and WCF Session( HTTPContext.Current.Session) work independently. How can I share Asp.net Session value to WCF Session and vise versa.
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).
I have a web service that calls another web service (not my design).The wrapper web service is our code the underlying web service is 3rd party.The issue is that when one of our apps calls the web service wrapper.. it opens a new connection to the underlying web service and that login time is around 10seconds! (3rd party issue)... the calls after the login are fast in testing.SO we are trying to have ONE login for all the calls to the underlying services. However our wrapper service is called one by one..I was thinking if there was a way to store the underlying web service connection in a cache (netbean?) I could reuse it for all web service connections to the 3rd party...
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?
Users can edit images downloaded from my site and then upload them back using a WCF Web Service. The problem is when users go to view images, they often do not see the latest versions because of caching. I'd rather not turn off the cache because it substantially reduces bandwidth. Is there a way to have the Web Service perform some action upon an upload to notify the next web client call that the image has changed?
I have more then 75 web application live on multiple surver and now I want to have single login(form authentication) for all. Anonymous user can access all the network but once login, they can manipulate info across network without login again and again.
I am showing thumbnail images in dataList on a page of my website. When i click on any image they open in big size. How i will share(Facebook). that particular big size image. My code is given below:
<script type="text/javascript"> var CurrentPage = 1; function GetImageIndex(obj) { while (obj.parentNode.tagName != "TD") obj = obj.parentNode; var td = obj.parentNode;
I have problem in maintaining the application objects in the server when it is deployed in the web farm.In our application i'm storing the sessionID and and the column value ( "tvktnx55vl5mzr453dmaehit " + "A101" ) in arraylist and storing it in application object. when i test this it is ok. but when we deploy it we have one issue that is we cannot share the application object in web farm.
I need to know what is Cache size. I've read solution on this site for more or less similar question but it partly serves me. As i know i can get values from PerMon, here is function
public static string getCacheSize() { PerformanceCounter pc = new PerformanceCounter("ASP.NET Applications", "Cache % Machine Memory Limit Used","__TOTAL__", true); return string.Format("{0:0.00}%", pc.NextValue()); }
1.it gives me percents when i need KB and there is no item closest to this one in PerfMon 2.it shows 70.5% used while all memory usage is about 50%
have a situation very similar to the one in this question:http://stackoverflow.com/questions/774695/selective-cache-clearing-across-load-balanced-servers-asp-netThe difference is that due to our hosting configuration, I am unable to address individual servers by IP address. Assuming I cannot access specific servers via web requests, is it possible to access the HttpContext of a web application running on the same machine? I'm thinking I could accomplish this with a windows service that I could address by machine name, or alternately a console application
