You have to use a more complex function like $.ajax() if you want to control caching on a per-request basis. Or, if you just want to turn it off for everything, put this at the top of your script: $.ajaxSetup ({ // Disable caching of AJAX responses cache: false });
Create a class that inherits from IActionFilter. public class NoCacheAttribute : ActionFilterAttribute { public override void OnResultExecuting(ResultExecutingContext filterContext) { filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)); filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false); filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches); filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache); filterContext.HttpContext.Response.Cache.SetNoStore(); base.OnResultExecuting(filterContext); } } Then put attributes where needed… [NoCache] [HandleError] public class AccountController : Controller { [NoCache] [Authorize] public ActionResult ChangePassword() { return View(); } }
If this is about .css and .js changes, one way is to to “cache busting” is by appending something like “_versionNo” to the file name for each release. For example: script_1.0.css // This is the URL for release 1.0 script_1.1.css // This is the URL for release 1.1 script_1.2.css // etc. Or alternatively do it … Read more
As far as I know a common solution is to add a ?<version> to the script’s src link. For instance: <script type=”text/javascript” src=”https://stackoverflow.com/questions/32414/myfile.js?1500″></script> I assume at this point that there isn’t a better way than find-replace to increment these “version numbers” in all of the script tags? You might have a version control system do … Read more
Preliminaries On modern computers, only the lowest level memory structures (the registers) can move data around in single clock cycles. However, registers are very expensive and most computer cores have less than a few dozen registers. At the other end of the memory spectrum (DRAM), the memory is very cheap (i.e. literally millions of times … Read more
Command-Option-Shift-K to clean out the build folder. Even better, quit Xcode and clean out ~/Library/Developer/Xcode/DerivedData manually. Remove all its contents because there’s a bug where Xcode will run an old version of your project that’s in there somewhere. (Xcode 4.2 will show you the Derived Data folder: choose Window > Organizer and switch to the … Read more
There are a couple of possibilities. One I like uses a stringstream as a go-between: std::ifstream t(“file.txt”); std::stringstream buffer; buffer << t.rdbuf(); Now the contents of “file.txt” are available in a string as buffer.str(). Another possibility (though I certainly don’t like it as well) is much more like your original: std::ifstream t(“file.txt”); t.seekg(0, std::ios::end); size_t … Read more

For IE9 and before Do not blindly copy paste this! The list is just examples of different techniques, it’s not for direct insertion. If … Read more
Disabling Chrome cache for website development
Python caches integers in the range [-5, 256], so integers in that range are usually but not always identical. What you see for 257 is the Python compiler optimizing identical literals when compiled in the same code object. When typing in the Python shell each line is a completely different statement, parsed and compiled separately, … Read more
