I want to store a high computational parameter to prevent its recomputation. But this parameter needs to be updated frequently to maintain consistency, should I use cache or a database or is there any other better solution for this?? I am using a...
All a Cache is is memory that is "closer to the processor" - often part of the same chip, and which is faster for the processor to access that having to go outside the CPU to main memory top get the value. And all frequent updates will do is...

Just to expand on Richard's answer - you can put the command timeout in the connection string in the same way that you were putting the connection timeout in, so this is a valid connection string (with the latest EF Core 6 packages): ...

I want to create a cache which evicts entries based on whether the cache size was hit or the TTL for the entry was hit. I couldn't find any code for a similar cache online using c++. Has anyone found any documentation for this? What I have...
If you're caching per user, browser cache is still your best friend. However, server-side cache does one thing browser cache cannot do, that is, shared cache for multiple users. In that case, you can simply use Application instead of Session to...

I have a SignalR project. Can i use cache some records? And how? What I have tried: I haven't any idea. codeproject alert: Both the question and 'What have you tried' must be between 30 and 50000 characters.
With such a poor question, the only answer you're going to get is a generic one. Yes. How is dependent on your requirements and existing code, which I seriously doubt you have. This also has nothing to do with SignalR. SignalR just handles...

No. Only the HTML is cached, it (generally) has no direct access to the data behind that. Think about it: to cache the whole site, it would need direct access to the DB server to cache a snapshot of the whole database which would be a massive...

Caching really isn't going to help much with that problem. First, loading all the records doesn't scale well, even if you cache the result. You're just transferring more and more data all in one block. The problem you have is that you're...
Recommendation is to never get your hands dirty for such performance-oriented parts of your application unless you have a solid experience/understanding. Oh, before I start the answer, I should suggest that migrating the code to .NET Framework 4...

check that you only calculate what you need and extract ANY constant value out of the loops and use const where possible. Like in for(int x = J / 4 * 4; x data[i * J + x] += mat1 -> data[i * K + k] * mat2 -> data[k * J + x];...

Quote: What is the best method to browser cache 10 lac records from SQL database in ASP.NET? The best method is to not do it. Loading the phone directory of your country in a droplist is a bad idea. Even a rate of 1000 records per second makes it 20 minutes to load. Advice: look at web sites on...

You want to cache 1,000,000 records on the client-side? One word: Don't. It sounds like you seriously need to re-think your design. The browser should be getting pages of data, only what the browser needs to show. Caching a million records when the client, typically, only needs to see or use a...

I would not suggest you to go for direct in-memory caching since with growing cache, the performance of application will degrade. However, you can consider using open source tools like Redis that allows you to cache data without causing any performance related issues and better management of...

Frameworks like Vue have the notion of “computed properties” – a way to derive some new, possibly complex data based on something passed in. This post covers how to achieve the same result in React.

I found the simple solution of my this problem. In Cache class I've add a static constructor and there I wrote the code of fetching cache data. As we all know static constructor can be called only once and it can't be called explicitly. So as soon as we try to read any variable of Cache class...

SaintModeCache is a thread safe in-memory cache wrapper for performance optimisation. It's able to continue serving stale content after expiry, whilst it repopulates the cache with a non-blocking single thread.

I do not think there is a perfect answer. We have some places where we tack on JavaScript new Date().getTime()to the end or our urls so that IE will think it is a page that has not been viewed before but we still have cache issues. It usually works but not all the time.The best option is...
Assuming SessionID is the asp.net session ID, you are on the right tracks but there is a problem with your implementation. If you update the js file in the middle of someone's session then their id...
I have stored a value in a key and cached it(using HttpRunTime.Cache.Insert) for a specific period of time(say 20 mins). Now I want to clear the cache whenever the cache is cleared from the browser the user. How do I do it(what code do I need to write on the server side for that)?What I have...
The server doesn't know when the user clears their cache so you can't react to it. You might have to do something like put a link to a handler on every page, and have it process the "If-Modified-Since" header. If that header is empty then this is the first time the user has requested the url...
Not sure which code block you want to keep, so I used the uncommented code.1. You should always use the using statement, as it will close the connection automatically or use try-catch-finally2. You forgot to assign the CommandText property3. You have an integer type in your parameter...

As you're using ASP.NET you probably need to create a button and/or page that will do this, and this will trigger the code on your ASP.NET server to call cache.Remove(key).Assuming clearing the cache is something you don't want normal users to do, the best approach is to put the page/button...
Scenario : I have an object (result set from DB) stored in memory cache (cache.Add(key, object)). This cache is having absolute expiration as cache policy. Some times I need to clear the object in cache (cache.Remove(key)) before the expiration. My application is running on IIS which should...

When your application initializes, have it open a connection and read the data into a Recordset, then close the connection. If the Recordset is kept in an application global variable (defined in global.asax, it has application lifetime, and is effectively cached.
