Need to redirect complete URL into redirected uri

PowerRangers If your intent is to redirect anything going to www.abc.com  with any URI path starting with "/find/redirect/" the following should work for you.

when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set HOST [string tolower [HTTP::host]]
    set URI [string tolower [HTTP::uri]]

    if { ${HOST} == "www.abc.com" } {
        if { ${URI} starts_with "/find/redirect/" } {
            
            HTTP::respond 301 Location "https://www.xyz.com/found/redirect?url=https://$HOST$URI"

        }
    } else {
        $DEFAULT_POOL
    }

}

Now if you want to redirect anything that connects to www.abc.com  to www.xyz.com/found/redirect?url=https:// <old_path> the following should do the job.

when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set HOST [string tolower [HTTP::host]]
    set URI [string tolower [HTTP::uri]]

    if { ${HOST} == "www.abc.com" } {

        HTTP::respond 301 Location "https://www.xyz.com/found/redirect?url=https://$HOST$URI"

    } else {
        $DEFAULT_POOL
    }

}

If I am missunderstanding the request please provide a real world example of one of the requests or rewording the question so we can have a different approach to the issue at hand.
