Hi ,

May i know if i can create a VIP with out default pool and do redirection based on uri to specific pool using LTM Policies and datagroups ? and May i know what happens when the condition fails ? Is there a a way we can return a generic error or response if the condition fails?

Thanks and Regards ,

Jagadeesh You absolutely can and it would be the following.

when HTTP_REQUEST priority 500 {

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

    if { [class match -- ${URI} eq CLASS-URI-TO-POOL] } {

        set TEMP_POOL [class match -- -value $URI eq CLASS-URI-TO-POOL]

        pool ${TEMP_URI}

    } else {
        HTTP::respond 400 content "Bad Request page" "Content-Type" "text/html" 
            return
    }

}
