What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. Well we made it to 30 editions of the 20LoL.  Soon we’ll break 100 iRule examples that are under 21 lines of code each.  Pretty neat stuff, if you ask me.  This week is the hoolio show, it seems.  The guy is just a monster in the forums, what can I say?  I sure am glad he’s on our side.  I’ve got three examples that I randomly pulled from the forums because I thought they were cool.  Only later did I realize that he had penned them all.  So big thanks yet again to Aaron and all his hard work to better the community.

20 Lines or Less #36 – Strip, parse, & change

What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. With the announcement of the BIG-IP LTM VE this week, the iRules world just got a little more interesting.  Between the new commands and features that have come out in the past several months, and now the ability to build and test iRules from your laptop, without having to connect to the internet/network at al...

DevCentral Top5 03/12/2010

This week I bring to you a full house of content, docs over blogs. To say there have been more than a few pairs on DevCentral lately though would be an understatement. The rush of content could be likened to an avalanche but without the messy death and destruction bits to deal with. From interviews to tech tips to blog posts to original songs pertaining to cloud computing (no, I'm not joking, and no, the link isn't in here…go find it yourself), DevCentral never seems to sleep these days, which is just how we like it. In case you're overwhelmed and looking for a place to get start... (more)

What Could You Do with Your Code in 20 Lines or Less?

What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. Here are a few more cool iRules from the forums. This week I’ve included one of the simplest, shortest iRules to ever make the 20LoL. It just struck me as something quite useful that I’m willing to bet several people will look at and say “oh, that’s handy” despite the fact that it’s not complex or long.  Keep... (more)

Friendly URL Redirection Scaling via iRules

The concept of a friendly URL is a pretty simple one. Basically you want to make things in your application, on your website, etc. easier to access. This stems from the fact that most applications these days make use of increasingly complex paths for a multitude of reasons. Whether it’s user specific content, auto generated pages or otherwise, typing in a URL that looks like “http://domain.com/a7391/users/0928179/events/live/release/20110403/regions.php?region=atl” isn’t something that’s easy or frankly even realistic for a user. I’m not going to remember that URL, and if I’m a... (more)
