Applying A Methodical Approach to Website Performance Issues

11 Nov

Last week the folks at PostSharp where kind enough to host me for a webinar on website performance.  For those that have attended my various performance talks over the years I'm a firm believer in following a process every time to resolve issues.  In this webinar, I discuss the beginning portions of approaching website performance issues, tips that are helpful for those with existing applications, or even those that are starting fresh.

24 Sep

Recent issues with a few clients I have encountered some "unusual" behaviors.  Either a situation where we had an unusual redirect situation, or we had pages that were showing HTTP 200 (success) status responses when in all reality the page truly didn't exist.  In the end, we had an IIS customization configured to handle certain types of 404's that DNN wouldn't handle, such as those for missing images, javascript files, and more.  Nothing that we haven't done for quite a while.
