irule help

Try putting your pool A URIs in one datagroup(

poolA_dg

); i.e. /news/events, /news/graphics,/aboutus/careers /aboutus/export, /aboutus/environment and all your pool B URIs in another datagroup(

poolB_dg

) and try this irule. It will be more efficient and should accomplish your goal.

when HTTP_REQUEST {
    if {class match [string tolower [HTTP::uri]] starts_with poolA_dg}{
        pool A
    }
    elseif {class match [string tolower [HTTP::uri]] starts_with poolB_dg}{
        pool B
    }
    elseif {[string tolower [HTTP::uri]] starts_with "/admin/"} {
        pool B member 1
    }
    elseif {[string tolower [HTTP::uri]] starts_with "/pdf/*"}{
        [HTTP::uri] [string range [HTTP::uri] 4 end]
        pool C
    }   
}
