iRule to Remove a part of uri and forward to a pool

Hi,

 

i am working on an iRule to Remove a part of uri and forward to a pool.

 

Eg:

 

xxx/yyy/abc/def should go to a pool 1 as

 

i want to remove xxx/yyy

 

Will the below work?

 

when HTTP_REQUEST {

 

set var1 "xxx/yyy"

 

if {([HTTP::uri] contains $var1) } {

 

set newUri [string map -nocase [list $var1 ""] [HTTP::uri]]

 

set HTTP::uri ${newUri}

 

pool Pool_1

 

}

    Hi Aditya,

    You were almost there, you don't need to set 

    HTTP::uri
    and the final 
    }
    to close the HTTP_REQUEST event was missing. I've also remove some necessary parenthesis and the was no advantage in setting 
    $newUri
    other than perhaps readability. 

    when HTTP_REQUEST { 
    set var1 "xxx/yyy" 
    if {[HTTP::uri] contains $var1} {
        HTTP::uri [string map -nocase [list $var1 ""] [HTTP::uri]]
        pool Pool_1
    }
}
