Cache Didn't Expire After A Minute
Mar 24, 2010This the code.
Cache.Insert(txtUserName.Text.Trim(), 1, null,
DateTime.Now.AddMinutes(1),
TimeSpan.Zero);
But Cache didn't expire after a minute.
This the code.
Cache.Insert(txtUserName.Text.Trim(), 1, null,
DateTime.Now.AddMinutes(1),
TimeSpan.Zero);
But Cache didn't expire after a minute.
Precondition: There's a web application that leverages ASP.NET security model. There's also an Active Directory (AD) integration component. It provides AD users and roles as if those are application's own users and roles. The relations like "is in role" between AD user and AD role are stored in AD domain, of course, but are cached by the web application.
Problem: Let's say AD user1 is a member of AD role1. When web application starts, it caches this relation. Now if the AD administrator removes user1 from role1 using AD console, the application doesn't know about this change - the cache entry is kept. This becomes a security hole because the role1 might have permissions the user1 should no longer have.
There are two сcontrary opinions how to solve this:
"Listen" to AD changes and trigger cache entry removal once the operation is detected on AD server - because we are responsible for correct AD component functioning Leave the cache untouched - because we didn't put the entry there and should not remove it either
Is there a method or something to force the expiration of all of the entries in the Cache collection of the HttpContext?

I have a Asp Mvc 2 site using forms authentication. When I run it locally I can log in and stay logged in indefinitely.
However when I put it on the server I seem to only stay logged in for a few minutes and then seems to be logged out. I have looked at the cookies and there are 2 which seem relevant:
.ASPXAUTH which is a session cookie .ASPXANONYMOUS which expires in 3 months.
When I refresh the page the cookies stay the same until I get logged out, when I seem to get a new .ASPXANONYMOUS cookie, but the .ASPXAUTH seems to be the same. It seems that I might be able to stay logged in until I do something after a certain amount of time. If I submit a form as soon as I am logged in then it works ok, but if I keep submitting data again and again then after a minute or so, one of the submits will happen as a logged out user and not as the user who was logged in, which all the other submits worked as. What might cause this behaviour and how can I track down what is different & change it so that I can stay logged in indefinitely?
its a single server, but after some more investigation and searching the likely candidate seems to be that I am using more than 100mb on the server and the application pool is getting recycled. I suppose now i need to know How can I check how much memory I'm using. What advice there is to reduce that.

I want to update a Panel after every 2 minute in asp.net mvc. For that i tried to impletment Update panel and Timer as we do in simple Asp.net .

View 6 RepliesI'm using ASP.NET MVC 3 with the Authorize attribute, but it keeps kicking me to the logon page after 1 minute, but even though my expiration is set to a very high value, it times out quickly. I check the cookie in my browser and its still there and not set to expire until about a month later, and it's set to be persistent, so I'm not sure why it keeps booting me. It only happens on my published location, locally it works just fine.
var ticket = new FormsAuthenticationTicket(username, true, 500000);
var encryptedTicket = FormsAuthentication.Encrypt(ticket);
var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
cookie.Expires = ticket.Expiration;
Response.Cookies.Add(cookie);
web.config:

<forms loginUrl="~/Account/LogOn" timeout="7200" slidingExpiration="false"/>

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?
What are the "optimal" parameters for creating an AppFabric cache when you will be storing session state in the cache? MSDN Cache-Related Commands
Powershell command line:
New-Cache [-CacheName] <String> [-Eviction <String>] [-Expirable <String>] [-Force [<SwitchParameter>]] [-NotificationsEnabled <String>] [-Secondaries <Int32>] [-TimeToLive <Int64>]
[code]...
Since I don't want my sessions to be removed unless the session has been abandoned either via code or Session Timeout...For eviction, I would think "None" and for expireable, I would think False.I have tested and calling Session.Abandon does remove the object from the cache. I have also tested to see if by extending my session, the session object in cache is also extended. This does seem to work the "correct" way.
We have a data driven ASP.NET website which has been written using the standard pattern for data caching (adapted here from MSDN):
public DataTable GetData()
{
string key = "DataTable";
object item = Cache[key] as DataTable;
[code]...
The trouble with this is that the call to GetDataFromSQL() is expensive and the use of the site is fairly high. So every five minutes, when the cache drops, the site becomes very 'sticky' while a lot of requests are waiting for the new data to be retrieved.
What we really want to happen is for the old data to remain current while new data is periodically reloaded in the background. (The fact that someone might therefore see data that is six minutes old isn't a big issue - the data isn't that time sensitive). This is something that I can write myself, but it would be useful to know if any alternative caching engines (I know names like Velocity, memcache) support this kind of scenario. Or am I missing some obvious trick with the standard ASP.NET data cache?
We are using HttpRuntime.Cache API in an ASP.NET to cache data retrieved from a database.
For this particular application, our database queries feature a LOT of parameters, so our cache keys look something like this:
table=table1;param1=somevalue1;param2=somevalue2;param3=somevalue3;param4=somevalue4;param5=somevalue5;param6=somevalue6... etc...
we have so many parameters that the cache key is several hundred characters long. is there a limit to the length of these cache keys? Internally, it is using a dictionary, so theoretically the lookup time should be constant. However, I wonder if we have potential to run into some performance/memory problem.
I have use Nhibernate in my MVC Project by me known, Nhibernate have cache on Session and Object. now, I want use HttpContext.Current.Cache (system.web) for cache data something in project. my code same that have problem, haven't it. and that's right or wrong.
View 2 RepliesI've got a web application that runs of a state server. It looks like soon it may need to distributed and there will be two web servers behind a load balancer.
This works great for session state but my next challenge is Cache
My application leverages heavily of cache. I understand ASP.Net 4.0 will be offering more here but nothing much has been said about the how too.
There are two challenges that I face
1). Each webserver will have its own copy of cache whereas it would be more efficient to put this to a third server the same as session state is put to state server.
2). The real challenge is keeping cache in sync if a simple dataset derived from the database is changed my code dumps that cache item and reloads the cache. That's all well on one webserver but webserver number two wont know to drop that particular cache item and reload it. This could cause some unexpected problems in the application.
For scenario number 2 I could attempt to do some smart coding so server number two knows to dump the cache and reload it.
My guess is someone else has already been here before and there's probably a better implementation approach rather than writing extra code.
Does anyone know how I could achieve the goal of keeping Cache in sync between multiple webservers or even better farm Cache management to another server?
I need to enable caching in my asp.net application, but I do not want to use the webserver's memory for holding cache objects. If I add the page directive for output caching will the page be stored in the asp.net cache object?
