问题 Here's my case: I have a table which contains a list of restaurants, each entry shows the results of inspections over time on a scorebar that is drawn using drawRect. When the user scrolls the table down and then up, so that scorebars with yellow and red squares are shown, previous scorebars pick up those squares. Dates are also drawn into previous scorebars. My problem lies in getting rid if the old squares. Shouldn't they be erased each time drawRect is called? I've placed three images

问题 I'm troubleshooting a caching issue on a set of secured pages and have realized that the Header needs to be modified for all Responses. As I put together a solution, I want to know the difference between HttpContext.Current.Response and Page.Response and when each object should be used in an app. Thanks. 回答1: Page.Response is simply a mapping to the HTTPContext when you are within the context of an HTML page. HttpContext.Current.Response simply allows you to get to the current context, when

问题 I am developing Web APIs using AWS Lambda, API Gateway and CloudFront. CloudFront is currently used as reverse proxy to some endpoints of API Gateway, cache behaviors are disabled at all. There are several frequently-used APIs, of which contents are rarely-updated (e.g. once a week or once a month) , therefore are candidates for caching for faster response time. However, I am wondering how to invalidate such CloudFront cache of frequently-used-but-rarely-updated dynamic content when their

问题 I know this question is very similar to this one, but I feel its different and specific enough to warrant its own question here. I've just inherited a Java web app project from a sole developer who left no documentation behind. Its a Spring MVC app with a basic package structure as follows: com.ourOrg.app.controllers ImageController ProgramController UserController com.ourOrg.app.otherPackages Each Controller class is just a POJO annotated with @Controller and @RequestMapping("/blah") .

问题 I have an application on node.js using sails.js as a framework. For displaying the informations to the user I have implemented some .ejs files. When navigating using links within the app menu, I receive a "304 - Nod Modified" response. Also, within headers in the response I see Etag , If-None-Match or Expires . After reading some posts, I have added the "app.disable('etag')" statement within /config/ express.js file in the customMiddleware function and etag and if-none-match are not sent

问题 I made a small site in Django but while checking the site performance with Google pagespeed I get the recommendation as Leverage browser caching but i cant find a way to achieve it in django 回答1: For views, you use the cache_control decorator.
