Help require in iRule creation

1. You need to better describe the problem.

    

2. Put forth at least a skeletal iRule that you developed and it is easier to assist.

    

Hi,

HTTP query parameters can be extracted with command:

set psn [URI::query [HTTP::uri] psn]
set pkproxy [URI::query [HTTP::uri] pkproxy]

Then, use these variables in redirect.

when HTTP_REQUEST { 
    set psn [URI::query [HTTP::uri] psn]
    set pkproxy [URI::query [HTTP::uri] pkproxy]
    if {([HTTP::path] equals /) && ([URI::query [HTTP::uri] target] equals "/rewards/download")}{
        HTTP::redirect https://xyz.pqr.com/ssoprecursor/home?psn=$psn&pkproxy=$pkproxy&returnurl=/onboard/home/setup&service=sbt
    }
}
