POCustom caching in ASP.NET
text
Body
copied!<p>I want to cache custom data in an ASP.NET application. I am putting lots of data into it, such as List<objects>, and other objects.</p> <p>Is there a best practice for this? Since if I use a static data, if the <code>w3p.exe</code> dies or gets recycled, the cache will need to be filled again.</p> <p>The database is also getting updated by other applications, so a thread would be needed to make sure it is on the latest data.</p> <h3>Update 1:</h3> <p>Just found this, which problably helps me</p> <p><a href="http://www.codeproject.com/KB/web-cache/cachemanagementinaspnet.aspx?fid=229034&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2818135#xx2818135xx" rel="nofollow noreferrer">http://www.codeproject.com/KB/web-cache/cachemanagementinaspnet.aspx?fid=229034&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2818135#xx2818135xx</a></p> <h3>Update 2:</h3> <p>I am using DotNetNuke as the application, ( :( ). I have enabled persistent caching and now the whole application feels slugish. </p> <p></p> <p>Such as a Multiview takes about 3 seconds to swap view.... </p> <h3>Update 3:</h3> <p><a href="https://stackoverflow.com/questions/115126/strategies-for-caching-on-the-web">Strategies for Caching on the Web?</a></p> <p>Linked to this, I am using the DotNetNuke caching method, which in turn uses the ASP.NET <code>Cache</code> object, it also has file based caching.</p> <p>I have a helper:</p> <pre><code>CachingProvider.Instance().Add( _ (label & "|") + key, _ newObject, _ Nothing, _ Cache.NoAbsoluteExpiration, _ Cache.NoSlidingExpiration, _ CacheItemPriority.NotRemovable, _ Nothing) </code></pre> <p>Which runs that to add the objects to the cache, is this correct? As I want to keep it cached as long as possible. I have a thread which runs every x Minutes, which will update the cache. But I have noticied, the cache is getting emptied, I check for an object "CacheFilled" in the cache. </p> <p>As a test I've told the worker process not to recycle, etc., but still it seems to clear out the cache. I have also changed the DotNetNuke settings from "heavy" to "light" but think that is for module caching.</p>
