caching

问题 In my app, Users profiles are open to the public and only updated by the profile owner. The profile URL is example.com/profile?user=@user.me And based on the docs https://firebase.google.com/docs/hosting/functions. I can cache the response JSON of the function, in this case, the public profile. Which will save me a lot of at cloud functions executions and Firebase database bandwidth And when the user updates his profile, I want to re cache the profile in the CDN. I think that can be done by

问题 I have a list that has some basic authentication on a document. The issue I am having is that the list is caching so the user will not see they have access unless I update the revision id. How do you show a non-cached list? if (req.userCtx.name === doc.permissions.owner) { return 'you have permission'; } else { return 'you do not'; } How I would imagine it done is by passing no-cache or update the ETAG or something of that sort in the header, but nothing seems to work. Here is an attempt I

问题 I am working on a web-based medical application and need to create a small in-memory object cache. Here is my use-case. We need to show list of requests submitted by people who need certain things (Blood, Kidney, etc.) and it's not going to be a huge list as in a given day request for blood or anything else will be a limited one. Please take into account that we do not want to use any caching API as it would be an overkill. The idea is to create a Map and place it in the ApplicationContext.

问题 I've just uploaded my silverlight webpage to my production webserver. The issue im having is that everytime I open the website in the browser it is downloading a new copy of the XAP. What could be causing this issue? 回答1: We have seen a similar problem appear when we entered Daylight Savings Time (British Summer Time in the UK). Check that the date/time on the server is not out of sync with the real world (usually by an hour). This may not be the cause of your problem, but best to check it

问题 I want to store items in the application cache so it's lazy loaded from the main layout view. I also want to be able to invalidate the cache, so if it's invalid, next time when the items-collection is requested, it's reloaded to that cache location. Here's what I've implemented: In the controller: protected IEnumerable<Slide> CachedSlides { get { return HttpContext.Application[SlidesCacheKey] as IEnumerable<Slide>; } set { HttpContext.Application[SlidesCacheKey] = value; } } private void

问题 My app keeps track of the state of about 1000 objects. Those objects are read from and written to a persistent store (serialized) in no particular order. Right now the app uses the registry to store each object's state. This is nice because: It is simple It is very fast Individual object's state can be read/written without needing to read some larger entity (like pulling out a snippet from a large XML file) There is a decent editor (RegEdit) which allow easily manipulating individual items

问题 Thanks for all the effort @Budius has made. Most part of image work of my app could be handled by Picasso/Glide, however, some images are displayed in a TextView by Html.fromHtml . And the images in TextView are also used frequently. However, I don't know how to implement getDrawable() method with Picasso/Glide for the ImageGetter passed to Html.fromHtml . Is it possible to share the same cache of Picasso/Glide for these pictures in TextView and other bitmaps? Or should I use an custom

问题 I'm using AFNetworking to download some images from the internet to my app. I'm using this code to download those images, AFHTTPRequestOperation *requestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:_linkString[indexPath.item]]]]; requestOperation.responseSerializer = [AFImageResponseSerializer serializer]; [requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { _imageView = [
