Can I ask what your use case is for lowercase uri? If you only care about the uri on the serverside, then you can just do this:

when HTTP_REQUEST {
    HTTP::uri [string tolower [HTTP::uri]]
}

If you need the client to see the lowercase URI in their browser, then you'll need to issue a redirect in the 

HTTP_REQUEST
event. However, you'll run into issues if it's not a 
GET
request (i.e. if a 
POST
is made). In the case of a GET, you could do this:

when HTTP_REQUEST {
    if { ([HTTP::method] equals "GET") && not ([string tolower [HTTP::uri]] equals [HTTP::uri]) } {
        HTTP::redirect [string tolower [HTTP::uri]]
    }
}
