I was recently asked to develop health monitors on my 10.2.4HF3 LTMs for our Exchange 2010 environment. Two of the three monitors were a bit challenging, so I wanted to share what I developed.  The monitors have been sanitized to protect our environment - modify them to fit yours. *** Active Sync *** This monitor was challenging me, until I stumbled across this statement for versions 10.2.x and 11.x in SOL2167: "When Basic Authentication is enabled by configuring a User Name and Pas...
The BIG-IP persistence cookie is a valuable configuration option that allows stateful applications to remain persistent to a specific node with no additional configurations within the application or on the server(s) by doing something like clustering. I hear application development teams refer to this as “sticky session” or “stick sessions”, but in reality this cookie has nothing to do with a user’s “application” session, but has everything to do with t...

Designing for Fine Grained Control and Monitor in a Load Balanced Environment – Gathering Information If you haven’t read Dynamic Intelligent Application Delivery Part 1, start there first, as this is not a standalone article and won’t make much sense without proper context.  All caught up now?  Splendid!  We use separate apps and a number of protocols to gather information from both the load balancing devices (F5 BigIP) and pool members (SunONE Directory) to aid in the dispatchi...

So now that we've got a vLTM installed and running, what can we do with it... There's a lot of examples out there of perl, python and Java. But not a lot of C...   I've also got an iPhone... Sadly we can't use my favourite SOAP programming language on the iPhone. In case you're wondering that's perl. Why perl? Well, mainly I'm a bit lazy, and perl does everything for you... Obviously you're more productive when that's the case, and the SOAP::Lite module has spoiled me for years I'm afraid...
Introduction The LTM VE is a lifesaver when it comes to developing applications that use the iControl interface, or for development of iRules. My main (personal) use of it so far is the development of applications that use the iControl interface. Although a real LTM appliance has until now been the obvious choice of development target, the sheer cost of dedicated hardware is a big barrier to independent developers. In this respect the LTM VE comes into its own as an easy to use anywhere device....

I recently had the pleasure of working on a Citrix 5.0 implementation and I wanted to share a few things that I learned during that setup.  As many of you know, there are two deployment guides that have been made available by F5 Networks in regards to setting up Citrix Presentation Server 4.5 in TMOS versions 9.x and 10.x.  They are excellent guides and the best thing about them is that you can utilize those guides to assist you in deploying Citrix XenApp 5.0, with a few exceptions of ...
