caching

问题 Our asp.net web application allows our (large) .css and .js files to be cached by client browsers for faster performance. But whenever we deploy a new version, we get phone calls from users about how the page looks messy and is full of javascript errors. It turns out, their browser didn't re-download the changed .css and .js files. Ctrl-F5 always fixes it. Is there any way to force a re-download after upgrade deployments, without setting it not to cache (and thus slowing our application down)

问题 I use Vuejs and I use workbox-webpack-plugin in order to make my site offline, I want to cache a folder which contains all my files (3 files) like picture below, but when I build my project(using Laravel-mix ). The main.js (which contains everything of Vue) cannot be cached in service-woker.js . I tried some ways to fix that but those didn't work. Does anybody face this issue, do you have any solution, many thanks! ->> 回答1: Why are you dealing it manually? Even though you can cache all static

问题 I was looking at a way for caching responses from an API endpoint developed in .NET Core. The request to the API must have a valid Authorization header as part the requirement. I came across a few articles mentioning that caching wouldn't be possible if the request contains Authorization header, which was a bit of surprise to me. So how should I tackle this problem? Are there any libraries that can possibly enable caching for this kind of scenario? 回答1: For The Authorization header must not

问题 We know that the direct-mapped caches are better than set-associative cache in terms of the cache hit time as there is no search involved for a particular tag. On the other hand, set-associative caches usually show better-hit rate than direct-mapped caches. I read that the modern processors try to combine the benefit of both by using a technique called way-prediction. Where they predict the line of the given set where the hit is most likely to happen and search only in that line. If the

问题 I'm working on some old(ish) software in PHP that maintains a $cache array to reduce the number of SQL queries. I was thinking of just putting memcached in its place and I'm wondering whether or not to get rid of the internal caching. Would there still be a worthwihle performance increase if I keep the internal caching, or would memcached suffice? 回答1: It seems likely that memcache (which is implemented on the metal) would be faster than some php interpreted caching scheme. However: if it's

问题 I need to disable the cache control headers in my Spring Security conf. According to the documentation a simple http.headers.disable() should do it, but I still see the Cache-Control:no-cache, no-store, max-age=0, must-revalidate Expires:0 Pragma:no-cache headers in responses. My current security config is: http.antMatcher("/myPath/**") // "myPath" is of course not the real path .headers().disable() .authorizeRequests() // ... abbreviated .anyRequest().authenticated(); Things I've tried so

问题 I have recently added cloudfront to my wordpress site hosted on AWS. At first my cart would not register any products being added to it - so I made a behaviour in cloudfront to not cache the cart, my account and checkout pages. Now my users can only add a single product at a time - after adding a second it overwrites what was added in intially. I believe it must be a problem with the caching behaviour of cloudfront. can anyone help me with what settings I need to get woocommerce to play nice

问题 I am trying to OCR an entire directory of pdf files using pytesseract and imagemagick but the issue is that imagemagick is consuming all my Temp folder space and finally I'm getting a cache error i.e "CacheError: unable to extend cache 'C:/Users/Azu/AppData/Local/Temp/magick-18244WfgPyAToCsau11': No space left on device @ error/cache.c/OpenPixelCache/3883" I have also written a code to delete the temp folder content once OCR'd but still facing the same issue. Here's the code till now: import

问题 I'm looking for a way to cache properties of an object. In my case, I suppose the object can change over the time, so the memoized value for the property should be flushable. In pure python, I want to have a behaviour like: class Foo: def __init__(self, text: str): self._text = text self._bar = None def flush(self): self._bar = None def update_text(self, text: str): self._text = text self.flush() @property def bar(self): if self._bar is None: print('Computing bar...') self._bar = f
