Possible to put parameter from an URL into a cookie?

Could be as simple as this. The request is http://your.domain.name/your/path?param1=this¶m2=that. The user would get session cookies param1CookieName=this and param2CookieName=that

when HTTP_REQUEST {
    set param1Cookie [URI::query [string tolower [HTTP::uri]] param1]
    set param2Cookie [URI::query [string tolower [HTTP::uri]] param2]
}

when HTTP_RESPONSE {
    if {$param1Cookie ne ""}{
        HTTP::cookie insert name param1CookieName value $param1Cookie
    }
    if {$param2Cookie ne ""}{
        HTTP::cookie insert name param2CookieName value $param2Cookie
    }
}
