iRule to manipulate url according to set condition

Hi Guys

 

 

I have started working recently on a BigIP and already amazed at its capabilities, but cant find the rule to accomodate the following request, so if any of you know about one, please shout.

 

 

The Condition

 

==================================

 

Variables

 

----------

 

LINK = business, work, play

 

EXT = html, aspx

 

 

Condition

 

IF URL =

 

http://www.foo.bar/$LINK/any_uri/anything.$EXT

 

 

TO CHANGE TO

 

 

http://www.foo.bar/web/$LINK/any_uri/anything/index.htm

 

==================================

 

 

Im really hoping to find a solution to this as my configs getting really large and this rule will eliminate the majority of the current rules in use.

 

 

Much Appreciated
