Colin and Jason spend some time on the lonely stretch of days between Christmas and New Years discussing their 2011 DevCentral top 10. Prior to the podcast, there was no discussion regarding what that list should look like, and naturally they approached it from different angles. Colin took a holistic approach, focusing on significant things rather than content alone, whereas Jason honed in on tech tips. So there are two lists. The links to the items discussed on the podcast are below. Enjoy, and Happy New Year! DevCentral has some exciting changes in store for 2012. ...
I thought I’d take a look this week at this interesting forum thread. User Carl Gottlieb posted requesting some guidance on preventing replay attacks in a scenario where users login into application 1 and the credentials for application 2 are passed in hidden fields (but in the clear) back to the client.

While we were down at Interop in Las Vegas last week, Colin and Joe had a chance to give a couple of short 5-minute presentations at the F5 booth. We just happened to have the camera handy so we shot Colin discussing using Geolocation with iRules. Most folks understand the need for making Geolocation based decisions for GTM/DNS based decisions, but Colin gives a few ideas on how to use it once the users have been directed to a specific datacenter.

This week Jason suggested a pretty awesome post regarding High Speed Logging (HSL). I thought I'd take this as an opportunity to briefly talk about HSL in iRules since it's a pretty cool feature that didn't get a ton of press when it went live. I then, of course, went on to talk about the post in particular and some of the questions being asked, and share a bit of Spark's ever awesome insight into iRules fu. ...

F5 Field Systems Engineer Patrick Chang explains an iRules solution that supports 2 active database instances in different data centers behind a web application. The goal is to provide the optimal user experience by load balancing requests for both the web/application tier and the database tier to a local data center whenever possible. Since cross-data center database replication takes approximately 20 seconds, one instance is preferred for database writes, and an iRule that reads and inserts time-stamped cookies reliably directs traffic to the closest database instance when possible, and to the...
