browser-cache

问题 I've noticed something interesting while monitoring the network communications between my browser and server. It has something to do with caching. Say I have a CSS file http://domain.com/main.css (used in unsecured pages), which can also be accessed via https://domain.com/main.css (used in secured pages). When I first load an unsecured page, the CSS file gets a 200 OK . When I reload the page (or go to another unsecured page), I get a 304 Not Modified . When I go to a secured page for the

问题 Basically, when I call DeleteUrlCacheEntry (which is part of the Wininet.dll API) I either get returned the number 1 (which means, deletion successful) or the number 0 (which meant, deletion didn't work). My question is, how can I find out why a deletion did not work? (that is, when a 0 is returned). I heard there is a GetLastError() function in C++, however I am using VB6 and apparently the GetLastError equivalent in VB6 is the Err.LastDllError property. After a DeleteUrlCacheEntry attempted

问题 I want to invalidate cached app.js after every single release. Short question : Is it necessary to physically rename(by gulp-rev, for example) app.js to app-a23ds.js every time or is enough to add param with hash in html like app.js?_=<build number> Description : I was sure before that is enought to write something like app.js?_=<build number> in index.html to load new file instead of cahed. But when I'm investigate this question deeper I found a few of huge solutions for this case. Like gulp

问题 I'm trying to test a website on the iphone simulator, I made some javascript changes and my javascript files are being loaded from cache. I see the old version files with safari web inspector, resources tab (on simulator window), also the network calls have status 304. I already disabled cache on macos Safari. I already tried deleting the safari cache on the simulator settings. Safari outside the emulator is loading the new files correctly (I emptied/disabled the cache). I'm using Simulator

问题 Some of sites are on shared hosting (Windows 2003 Server), so I have no way to access server configuration. I read everywhere about leverage browser caching, expecially for static files (jpg, css, js, etc.) but... how to do this in my case? The hosting has .NET installed, could a web.config file help in some way? If yes, how? 回答1: Here is how I did on my site that is on a shared host. I believe the cacheControlMaxAge is as follows days:hours:minutes:seconds but dont quote me. <system

问题 As of jQuery 1.5, the ajax methods now correctly handle 304 Not Modified responses by calling the success() handler, as per the W3C spec for XMLHTTPRequest. This allows your application to treat the request as being successful, even if the server didn't actually return any data (because you already have the latest data cached). For a normal (uncached) GET request, the success handler is called with the following args: data: { the data from the server } status: OK jqXHR: status: 200 statusText

问题 This question already has answers here : Using <meta> tags to turn off caching in all browsers? [duplicate] (6 answers) Closed 6 years ago . I have the following to refresh my page when clicked on href. <a href="javascript:history.go(0)">Click to refresh the page</a> I have this <meta http-equiv="no-cache"> in the head tag. Even then I am getting a cached copy. How can I avoid loading cached copy? 回答1: instead of javascript:history.go(0); you may use javascript:window.location.reload(); 回答2:

问题 When aggressively caching CSS and other files, you can force the user to update to the latest version of the stylesheet by renaming the file and linking to the new copy (eg, style.123.css renamed to style.124.css ). A different method often used instead of renaming the file is to pass a URL parameter, (eg, style.css?ver=123 which is later changed to style.css?ver=124 ). Do all browsers support the latter method for downloading a new copy of the stylesheet? Are there any disadvantages to using

问题 How to remove Angular template cache once user clicks on logout? We did thorough research and tried to implement most of the solutions available out there. we tried following HTML Meta Tags <meta http-equiv="Cache-Control" content="no-cache" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> Server side res.setHeader('cache-control', 'no-cache', 'no-store', 'must-revalidate'); Javascript We tried to delete browser history as specified on this blog

问题 Before Webpack I would always rely on the following pattern for "cache-busting": <script src="foo.js?cacheBust=12345" /> where 12345 was a token the sever generated for me on every build (it could be a Git hash, although in my case it isn't). With Webpack I now have two files: build.js and chunk.1.js . Since I bring the first one in with a normal script tag I can use the above pattern: <script src="build.js?cacheBust=12345" /> However, at that point build.js goes and fetches chunk.1.js , and
