CSS and Javascript files don't change very often, so I want them to be cached by the web browser. But I also want the web browser to see changes made to these files without requiring the user to clear their browser cache. Also want a solution that works well with version control system such as Subversion....
Currently I know of only two ways to cache data (I use PHP but I assume that the same will apply to most languages). Save the cache to a file Save the cache to a large DB field Are there any other (perhaps better) ways of caching or is it really just this simple?...
I am in the process of figuring out a cache strategy for our current setup, currently have multiple web servers and wanted to know what is the best way to cache data in this environment. I have done research about MemCache and the native asp.net caching but wanted to get some feedback first. Should I go with a Linux box if I use MemCache...
Recently I have been investigating the possibilities of caching in ASP.NET. I rolled my own "Cache", because I didn't know any better, it looked a bit like this: public class DataManager { private static DataManager s_instance; public static DataManager GetInstance() { } private Data[] m_myData; p...
Does anybody have experience working with PHP accelerators such as MMCache or Zend Accelerator? I'd like to know if using either of these makes PHP comparable to faster web-technologies. Also, are there trade offs for using these? ...
Can a (||any) proxy server cache content that is requested by a client over https? As the proxy server can't see the querystring, or the http headers, I reckon they can't. I'm considering a desktop application, run by a number of people behind their companies proxy. This application may access services across the internet and I'd like t...
For a .NET component that will be used in both web applications and rich client applications, there seem to be two obvious options for caching: System.Web.Caching or the Ent. Lib. Caching Block. What do you use? Why? System.Web.Caching Is this safe to use outside of web apps? I've seen mixed information, but I think the answer is m...
What's the best way to handle a user going back to a page that had cached items in an asp.net app? Is there a good way to capture the back button (event?) and handle the cache that way? ...
This is mostly geared toward desktop application developers. How do I design a caching block which plays nicely with the GC? How do I tell the GC that I have just done a cache sweep and it is time to do a GC? How do I get an accurate measure of when it is time to do a cache sweep? Are there any prebuilt caching schemes which I could ...
I'm trying to improve performance under high load and would like to implement opcode caching. Which of the following should I use? APC - Installation Guide eAccelerator - Installation Guide XCache - Installation Guide I'm also open to any other alternatives that have slipped under my radar. Currently running on a stock Debian Etch w...
We are currently working in a private Beta and so are still in the process of making fairly rapid changes, although obviously as usage is starting to ramp up, we will be slowing down this process. That being said, one issue we are running into is that after we push out an update with new JavaScript files, the client browsers still use t...
While writing a custom IHttpHandler I came across a behavior that I didn't expect concerning the HttpCachePolicy object. My handler calculates and sets an entity-tag (using the SetETag method on the HttpCachePolicy associated with the current response object). If I set the cache-control to public using the SetCacheability method everyth...
So I just fixed a bug in a framework I'm developing. The pseudo-pseudocode looks like this: myoldObject = new MyObject { someValue = "old value" }; cache.Insert("myObjectKey", myoldObject); myNewObject = cache.Get("myObjectKey"); myNewObject.someValue = "new value"; if(myObject.someValue != cache.Get("myObjectKey").someValue) myObj...
I maintain several client sites that have no dynamic data whatsoever, everything is static asp.net with c#. Are there any pitfalls to caching the entire page for extreme periods of time, like a week? Kibbee, We use a couple controls on the sites (ad rotator, some of the ajax extensions) on the sites. They could probably be completely w...
We've been running eAccelerator on each of 3 webservers and are looking to move to a memcache pool across all 3, hopefully reducing by about 2/3 our db lookups. One of the handy things about eAccelerator is the web-based control interface (control.php), which has proved very useful when we've had to flush the cache unexpectedly, quickly...
Is there a simple way to cache MySQL queries in PHP or failing that, is there a small class set that someone has written and made available that will do it? I can cache a whole page but that won't work as some data changes but some does not, I want to cache the part that does not. ...
We've just started using LINQ to SQL at work for our DAL & we haven't really come up with a standard for out caching model. Previously we had being using a base 'DAL' class that implemented a cache manager property that all our DAL classes inherited from, but now we don't have that. I'm wondering if anyone has come up with a 'standard'...
What is the best approach to implement distributed caching with .NET? Edit: I was looking for a general caching schema for internal and external applications ...
I know in certain circumstances, such as long running processes, it is important to lock ASP.NET cache in order to avoid subsequent requests by another user for that resource from executing the long process again instead of hitting the cache. What is the best way in c# to implement cache locking in ASP.NET? ...
I have a file which is an XML representation of some data that is taken from a Web service and cached locally within a Web Application. The idea being is that this data is very static, but just might change. So I have set it up to cache to a file, and stuck a monitor against it to check if it has been deleted. Once deleted, the file will...
