caching

问题 Quick question: I have a service worker that caches a page from subdomain "domainB.project.company.com" Expl: domainB.project.company.com/mypage.html This works, I can see the assets + html being cached in my Chrome Dev Tools. Then I have another subdomain "domainA.project.company.com" with a page domainA.project.company.com/hello.html so, both pages have the same host... Now: the mypage.html is fully cached. Why - when offline - isn't the "mypage.html" shown when navigating to that url from

问题 Hello Stack Overlords! I'm currently trying to put together a little coding project. Something simple, but I'm having a rather difficult time. The objective, clear out three cells once the time of day, based on one of those cells, passes. Essentially - G9 contains the the time I want the cells to be cleared. Once it has gone past the time of day specified in G9, I'd like cells D6, D9 and G9 cleared. I've set up a way of doing this using an IF statement, both from the sheets side, and scripts

问题 I have setup a WebViewActivity which gets the URL from the intent. I have setup an onClickListener for my Recyclerview which opens the WebViewActivity and loads the URL. However the WebView does not cache each an every page it opens. What changes should i make in the code? WebViewActivity.java public class WebViewActivity extends AppCompatActivity { WebView myWebView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout

问题 I have a function that reads map tile images. I want to keep track of whether or not a certain image has already been cached. I'm using this function from this thread: function is_cached(src) { var image = new Image(); image.src = src; return image.complete; } This was working great. But then I needed to do some image processing. In order to copy the image data to a canvas and process it pixel by pixel, I need to use CanvasRenderingContext2D.drawImage(image, 0, 0) . But it bugs me with a

问题 I have an Angular 8 application for which I have had caching problems during deployment of new releases. Basically I noticed that when using ng build --prod , the outputHashing option is set to all in my angular.json . Therefore all files generated by ng build have a content hash in their names, which is great for two reasons: the browser can safely long-term cache the files of my application (if the content of the file changes in a new release, the name changes and therefore the file is

问题 Is there anyway I can flush iCache in x86 architecture ? Like WBINVD which will invalidate and flush all the cachelines in data cache. 回答1: According to the docs, wbinvd flushes and invalidates all caches , not just data and unified caches. (I'm not sure if that includes TLBs if you ran it with paging enabled.) What are you trying to test? L1i miss / L2 hit for code-fetch? I don't think it's possible to purposely flush just the I-cache without also flushing all levels of cache. You could

问题 I'm learning my way around EF, and I know caching is faster than a round trip to the DB for things like state, country, etc. But I'm not sure how to implement it. I was looking at this post (entities from local cache) that mentioned an extension, but is there something built in I should leverage? I'd like to have a function like this that wouldn't have to go to the db every time: public static int GetCountryId(string countryCode = "US") { if (countryCode == string.Empty) countryCode = "US"; /

问题 I have two projects called A and B that have complete working CMakeLists.txt projects, and each project can be built completely without errors. I would like to have a master project defined in CMake that will build both A and B (and maybe a hundred other things eventually). My top level CMakeLists.txt project looks like add_subdirectory(A build-A) add_subdirectory(B build-B) and CMake can parse all the files and make can start building just fine. The problem is that project A is for one

问题 I want to to configure my cache size. I am using @EnableCaching . Here is my cached repository. VendorRepository public interface VendorRepository extends Repository<Vendor, Long> { @Cacheable("vendorByUsername") Vendor getVendorByUsername(String username); @CacheEvict(value = {"vendorByUsername", "vendor", "vendors"}, allEntries = true) Vendor save(Vendor vendor); @Cacheable("vendor") Vendor findOne(Long id); @Cacheable("vendors") List<Vendor> findAll(); } It is working good right now but I
