Bandwidth limit using iRule

I'm having a problems with bandwidth limits using rate shaping on BIG-IP LTM. I want to configured rate shaping for one HTTP Service that has three websites on single server IIS6. Example with domains and bandwidth limit as following:

 

www.abc1.com has a bandwidth is 300K;

 

www.abc2.com has a bandwidth is 500K;

 

www.abc3.com has a bandwidth is 1M;

 

 

Must I write a irule program? But I haven't had a experience with iRule yet. So please help me the way to I can do it.->thanks so much.

    Hello,

    You could use an iRule that inspects the HTTP host header value and applies a rateclass to the request. Here is an example:

    
switch -glob [string tolower [HTTP::host]] {
   www.abc1.com* {
      rateclass class_200K
   }
   www.abc2.com* {
      rateclass class_500K
   }
   www.abc3.com* {
      rateclass class_1M
   }
   default {
      rateclass class_200K
   }
}
