splitting a domain apart; can I used awk in an iRule?

Hi Adam,

 

 

No, you can't use awk from an iRule. But you can use string functions or a regex to do this. You could use the getfield string function for this to avoid the overhead of a regex:

 

 

set subdomain [getfield [HTTP::host] "company.com" 1]

 

HTTP::replace Host "$subdomain.company.com"

 

 

For details on the getfield command, you can check the wiki page:
