LTM VE 10.2.3: HTTP::uri

OK, try this, I've just added some logging, made the URI lowercase everywhere and reduced the size of the switch;

when HTTP_REQUEST {
    set originaluri [string tolower [HTTP::uri]]

    switch -glob [string tolower [HTTP::uri]] { 
        "/cm/" { 
            set SELECTED_POOL "LPAGE_ALERTAS"
        } 
        "/delivery/imanager" -
        "/delivery/wifi" { 
            set newuri [findstr $originaluri "/delivery" 9] 
            HTTP::uri $newuri
            set SELECTED_POOL "LPAGE_DELIVERY_CMP"
            log local0. "Rewriting URI from $originaluri to $newuri"
        } 
        "/delivery" { 
            set SELECTED_POOL "LPAGE_DELIVERY_CMP"
        }
        default { 
            HTTP::respond 403
            log local0. "No URI match, sending a 403 response"
        } 
    } 
}
