I'll be presenting to the Ann Arbor .Net Developer's Group in two weeks on ASP.NET Caching Best Practices.  The meeting starts at 6pm at SRT Solutions in Ann Arbor.  You can find more information about the group and meeting location here: AADND.org

Ran into an interesting bug today with one of my applications.  A user control that provides messages based on a user's account was showing the wrong information to other users in our testing.  The user control was set up with an output cache directive and a VaryByParam=''*'' setting, yet it was showing other users' messages (one in ...

Tuesday night I gave a presentation on caching in ASP.NET (with a bit of async performance tips thrown in at the end) to the Arizona .NET User Group in Phoenix, Arizona.  A lot of the demos were similar to ones I've given before, including in my recent DNRTV Show on Caching.  I've posted the samples from Tuesday night's talk here, which ...

I'm on dnrTV this week with a show about Caching in ASP.NET, one of my favorite topics.  I think the whole show is a bit under an hour and I go through a bunch of demos and show off some of the less-well-known features of caching, such as cache profiles, programmatic output cache invalidation, and the Substitution control that lets you have ...

I'm in the midst of wrapping up a multi-year long project to replace the advertising engine used to host sponsored ads on a few dozen .NET web sites.  This system traces its "lineage" back to an old ASP application written in 2001 (it served its first 207 impressions on 31 March 2001), and has since been upgraded to ASP.NET ...

Peter Bromberg recently wrote an article on refreshing the ASP.NET cache, which referenced my ASP.NET Caching Best Practices article on MSDN.  In my original article, I lamented the general uselessness of the CacheItemRemovedCallback feature, and wished for a CachedItemExpiredButNotRemovedCallback.  Sadly, this feature is still ...

In my last post I wrote that I would be speaking in Moscow this week - well, I did so Monday night and it went quite well I thought.  I have uploaded the presentation and demo code from the presentation as promised - sorry it took a couple of days but I didn't get back online until I returned home to Ohio, USA.  Thank you Gaidar ...

I’m at the MVP Summit this week in Seattle and one of the things this provides an opportunity for is providing feedback to the product teams.  I certainly have plenty of ideas of my own for new features I’ve been longing to see in ASP.NET, as well as fixes for some annoyances.  If you have ASP.NET feature requests of your ...

Many of you know that I’m very much into high performance and scalability techniques.  One thing you need to remember when applying performance tweaks is that as your application changes, your performance optimizations may need to change and evolve with it.  Let me demonstrate this with a case in point. On ASPAlliance.com, a ...

I’ll be speaking at the Arizona .NET user group on 7 March 2007 about Caching and Performance.  More information here.  The session’s description is: This session focuses on fundamentals of performance and scalability design, testing, and optimization, with an emphasis on distributed architectures and data driven ...
