8 min readCaching is a technique used to store frequently accessed data in a faster and more efficient manner. In C++, caching can be implemented using data structures like hash maps, sets, and lists to store the cached data.One common way to implement caching in C++ is to use a hash map to store the key-value pairs where the key represents the data being cached and the value represents the cached data itself. This allows for quick access to the cached data by looking up the key in the hash map.

3 min readTo prevent an HTML5 page from caching, you can add a meta tag in the head section of your HTML document with the following attributes: What is cache header in HTML5?In HTML5, a cache header is a directive that specifies how a web page or resource should be stored in the browser cache. This header is included in the HTTP response from the server and tells the browser how long it should retain a cached copy of the resource before checking for updates.

4 min readCaching in MongoDB can be implemented using various strategies such as in-memory caching, Redis caching, or application-level caching. In-memory caching involves storing frequently accessed data in memory to reduce the number of database queries. Redis caching can be used to store frequently accessed data in a separate Redis instance, which can help reduce the load on the MongoDB database.

4 min readTo disable MySQL query caching, you can do so by modifying the MySQL configuration file (my.cnf). Locate the section that enables query caching and set the values to 0 or comment out the lines. You can find the query_cache_type and query_cache_size parameters in the configuration file. Once you have made the changes, save the file and restart the MySQL service for the changes to take effect.

6 min readUnit testing a service that uses caching can be challenging, as caching introduces an extra layer of complexity to the testing process. One approach to unit testing a service that uses caching is to use mocking frameworks to simulate cache behavior.Mocking frameworks allow you to create fake cache objects that mimic the behavior of a real cache. This enables you to isolate the service being tested from the actual cache implementation, making it easier to test the service in isolation.

5 min readSystem.Web.Caching in ASP.NET is used to store and retrieve data in memory to improve the performance of web applications.To use System.Web.Caching, you first need to create an instance of the Cache class and store data in it using a unique key. You can then retrieve the data using the same key.You can set various properties such as expiration time and priority when storing data in the cache.

8 min readTo leverage browser caching in Django, you can set the cache control headers for your static files in the HTTP response. This tells the browser how long it should keep certain files cached before checking for updates. You can do this by using the HttpResponse class in Django and setting the Cache-Control header with the max-age directive to specify the time in seconds that the file should be cached.

6 min readTo verify that Apache caching is working, you can use a web browser developer tools or a command line tool like cURL to check if the caching headers are being sent and received correctly. You can also monitor the server logs to see if the cached content is being served to clients instead of making repeated requests to the server. Another way to verify Apache caching is working is to check the response times of requests to see if they are faster when content is being served from the cache.

5 min readA Python decorator for caching is a function that wraps another function in order to store the results of the wrapped function in a cache. This can be useful when a function's output is expensive to compute and it is likely to be called multiple times with the same input.To create a caching decorator in Python, you can define a function that takes the original function as an argument and returns a new function that wraps the original function.
