Web redirections with data group fail if URI contains "?"

text

I have imported a huge preformated txt file of redirections in order to be managed in a data-group and be used in an irule applied to our vserver.

All seems to work fine and redirections are being managed in a right way. However I´m noticing this kind of redirections in the original txt file are being managed fine:

"/wines/mostsold/themostsold.asp" := "www.ourshop.com/shop/gourmetshop/",

But redirections with "?" character contained in the URI are not being managed like this one:

"/wines/product/product.asp?pRef=13345204286" := "www.ourshop.com/shop/gourmetshop/browse/productDetailCult.jsp?productId=A10111941",

This is the irule applied to our vserver:

when HTTP_REQUEST {
    if {[TCP::local_port] == 443} {
        set protocol "https"
    } else {
        set protocol "http"
    }

    set newuri [class match -value [string tolower [HTTP::uri]] equals redirections_gourmet301]
        log local0. "URI IS: $newuri"
    if {$newuri ne ""} {
        HTTP::respond 301 noserver Location "$protocol://$newuri"
        unset newuri
    } else {
               log local0. "URI IS NOT FOUND ON DATAGROUP"
        }
}

It seems URI is not found on datagroup when URI contains "?" character. This kind of redirections managed in a irule containing IF URI equals...THEN redirect... sentences are managed fine, but i don´t know why they are not working fine in a datagroup.

Anybody coul tell my what is happening? Am i doing something wrong??

Thanks.
