iRule for redirect from URL to URI

I'm extremely new to iRules (2nd day) and am asking for help. I am having difficulty getting an iRule to take a url and redirect (or append) that same url with a "/abc"

 

Here is my current rule:

 

when HTTP_REQUEST { if {([string tolower [HTTP::host]] equals "http://host.123.com")}{ HTTP::header replace Host "http://host.123.com/abc" } }

 

Pretty straightforward, right? I thought so, but what happens is when I go to "http://host.123.com" and want it to send me to "http://host.123.com/abc," it does nothing and simply keeps me at "http://host.123.com"

 

Any direction here is greatly appreciated. Thank you for your time

    Hi Nitass,

     

    Thank you for the quick reply. I was able to make it work using another answer to another question you had posted.

     

    Your answer, when HTTP_REQUEST { if { [HTTP::host] eq "host.123.com" and [HTTP::uri] eq "/" } { HTTP::uri "/abc" } } was very close to what I needed to achieve. To note what I am using (and it is working): when HTTP_REQUEST { if { [HTTP::uri] eq "/" } { HTTP::redirect "http://host.123.com/swbc" } }

     

    Thanks againg for you help.
