I'm in the process of improving the security of an ASP.NET app and have modified HTTP response headers to clear the cache, disallow storage of the cache, and expire the page immediately on many secured pages. Since modern day browsers support Auto-Complete functionality, I am tackling this piece of the puzzle that allows users to view p...

For many interactions, I would like to simply modify the value in cache, and only synchronize it with the...

Simplifying below :) First, a client record has a many-to-one relationship with a collection of services, that is, a single client may have multiple services associated with it.

However, when using a secure connection I get the "Internet Explorer was not able to open this Internet Site". I know that the problem has to do with my HttpCaching policy. The following MS Support document explains the issue...
Hi, I would like to create a caching system that will bypass some mechanisms in order to improve the performance. I have some examples: 1-) I have a dynamic PHP page that is updated every hour. The page content is same for every user. So in this case I can either: a) create an HTML page, and that page can be generated every hour. In ...
Are there any implementations of a static size hashtable that limits the entries to either the most recently or most frequently used metadata? I would prefer not to keep track of this information myself. I know most caching components keep track of this, but I would rather not introduce quite a lot of new dependencies. ...

I have a project for school and I have to use Java. Recently I found play framework and I want to try to use it. It's easy enough for a quick start, but I ran into a problem with session. Being stateless by its nature, play sends entire session to user in cookie and receives it on next request, so it allows only limited amount of data i...

I'm trying to use Amazon S3 and Amazon Cloudfront CDN to deliver the jar files of my applet application. I'm seeing several cache misses of my jars by the java plugin. This is a show-stopper for me, as the size of my application is around 3Mb, and I can't make my customers re-download the application every time. The problem is that, du...
I am working on a ASP.NET web application that uses the Session heavily. Recently, we have experienced negative performance due to excessive memory consumption. I am interested to know if there are any tools to run against the server to check what is being stored by the web app in the Session/Cache/Application to determine the size of th...
I used to have a situation where I hit the database a every time I needed information on an employee. Then I taught myself about data caching and have since cleared up that problem substantially. Now, I'd like to take it to the next level. I'd like to reduce load times by caching my object instantiation. I'm not sure that I'm being cle...

I more or less stumbled upon this by accident looking in the Firefox Cache: http://localhost:8080/jquery-ui-1.7.2.custom.css;jsessionid=A8483FBF3BB6DDA499E06210BE0D612C My big question is, ...
We have an ASP.NET application in which on the master page we have a user control that displays the most recently accessed entities by the user. To prevent database trips for every page load, we have enabled the caching for this user control by setting the outputcache directive as follows: <%@ OutputCache Duration="1200" Shared="true" ...
Just wondering how you guys manage your cache invalidations. Given that there might objects (hundreds and thousands) in the cache that might be triggered by different algorithms or rules. How do you keep track of it all? Is there anyway you can reference the relationships from a table in the database and enforce it somehow? Do bear w...
