caching

问题 I want to know how can okHTTP response from Web server (which returns json data) be cached? I want my app to download all the data needed for RecycleView and cache it once the user runs the app first time - and avoid re-downloading and parsing all the same data from Web server, if data has not changed. I tried to get response headers, but this is what I get: Request URL: https://somedomain.com/wp-json/?categories=3&per_page=100&status=publish Request Method: GET Status Code: 200 OK Remote

问题 This question comes in context of a section on virtual memory in an undergraduate computer architecture course. Neither the teaching assistants nor the professor were able to answer it sufficiently, and online resources are limited. Question: Suppose a processor with the following specifications: 8KB pages 32-bit virtual addresses 28-bit physical addresses a two-level page table, with a 1KB page table at the first level, and 8KB page tables at the second level 4-byte page table entries a 16

问题 I am creating a custom cache object for data that is relatively static and is periodically updated from the DB. I have chosen to use a strongly-typed DataSet to store the cached data. Now, access for reading and refreshing (clients cannot write to the cache, only refresh it) to the custom cache object is synchronized via ReaderWriterLockSlim. HOWEVER, I want to ensure that clients of the cache cannot corrupt the data (DataTables, DataRows, etc.) within the strongly-typed data set by

问题 The same Azure Redis cache is getting connected from local machince. The port 6380, on which cache is running is open in firewall of both inbound and outbound in the VM. I tried in both NodeJs and Java. Both are connecting to remote Azure Redis from local and the exact same code for NodeJS and Java is not connceting to Azure Redis cache from VM. Java config: spring.redis.host=my-cache.redis.cache.windows.net spring.redis.password=<password> spring.redis.port=6380 spring.redis.ssl=true NodeJS

问题 I'm trying to serialize ClassA into JSON and then deserialize and map it into ClassB only on similar attribute, ignoring a lot of checking. Lets say I have public class First{ private String attribute1; private String attribute2; private String attribute3; } public class Second{ private Int attribute1; private String attribute2; private String attribute4; } What am I expecting is mapping an object of Second like { "attribute2": "value2" } Is it possible? I need to do this because I have a

问题 I haven't found a clear answer: does the control unit itself fetch pre-defined instructions to execute a cache eviction, or does the operating system intervene? If so, how? 回答1: Which part of the computer manages cache replacement? Typically; a cache manages cache replacement itself (its not done by a separate part). There are many types of caches where some are implemented by software (DNS cache, web page cache, file data cache) and some are implemented in hardware (instruction caches, data

问题 There's a similar question on here, but the answers are over 2 years old and I can't get it to work. If I'm missing something - please let me know. Bottle.py caching templates despite being in debug mode Whenever the browser points to 0.0.0.0:8080/16boxes, I need to prevent caching. The Bottle docs say when in Debug mode, caching is disabled, but that isn't the case for me unfortunately. Here is my hello.py code in question: @route('/16boxes') def send_static(): response.set_header('Cache

问题 I have a service worker that I want to return an offline page if you're offline. I realized you have to cache the offline page first, so I did that. When I had it cached, and I used chrome dev tools to throttle the network to offline, it showed the default offline page! I don't know how to bring up the page when it is offline. I'm on a chromebook if that would change anything. Here's my code (by the way I am completely new to service workers): this.addEventListener('install', function(event)
