You just need a unique string. It doesn’t have to be Hash. We use the LastModified date of the file and get the Ticks from there. Opening and reading the file is expensive as @Todd noted. Ticks is enough to output a unique number that changes when the file is changed. internal static class BundleExtensions … Read more
In Linux (you never mentioned which OS you’re on, so this could be relevant) you can create block devices from RAM and mount them like any other block device (that is, a HDD). You can then create scripts that copy to and from that drive on start-up / shutdown, as well as periodically. For example, … Read more
From MSDN: The main differences between the Cache and MemoryCache classes are that the MemoryCache class has been changed to make it usable by .NET Framework applications that are not ASP.NET applications. For example, the MemoryCache class has no dependencies on the System.Web assembly. Another difference is that you can create multiple instances of the … Read more
Pop your cached query into Django’s cache: from django.core.cache import cache cache.set(‘key’, queryset) Then create a context processor to add the value of the cache to all templates: # myproject/myapp/context_processors.py from django.core.cache import cache def cached_queries(): return {‘cache’, cache.get(‘key’)} Then add your context processor in your Django settings file: TEMPLATE_CONTEXT_PROCESSORS += ( ‘myproject.myapp.context_processors.cached_queries’ ) Now … Read more
I think the answer might depend on the type of web applications you are running. I had to make this decision myself two years ago and couldn’t decide between Zend Optimizer and eAccelerator. In order to make my decision, I used ab (apache bench) to test the server, and tested the three combinations (zend, eaccelerator, … Read more
The key to good performance with Java is to write idiomatic code, rather than trying to outwit the JIT compiler. If you write your code to try to influence it to do things in a certain way at the native instruction level, you are more likely to shoot yourself in the foot. That isn’t to … Read more
As far as I know, a forced update like this is not directly possible. You might be able to reduce the DNS downtime by reducing the TTL (Time-To-Live) value of the entries before changing them, if your name server service provider allows that. Here’s a guide for less painful DNS changes. A fair warning, though … Read more
by this: <meta http-equiv=”expires” content=”0″> Setting the content to “0” tells the browsers to always load the page from the web server.
This solution works for django versions before 1.7 Here’s a solution I wrote to do just what you’re talking about on some of my own projects: def expire_view_cache(view_name, args=[], namespace=None, key_prefix=None): “”” This function allows you to invalidate any view-level cache. view_name: view function you wish to invalidate or it’s named url pattern args: any … Read more
The time the browser considers a cached response fresh is usually relative to when it was last modified: Since origin servers do not always provide explicit expiration times, a cache MAY assign a heuristic expiration time when an explicit time is not specified, employing algorithms that use other header field values (such as the Last-Modified … Read more
