Regular Expression

Perhaps then a data group:

when HTTP_REQUEST {
    if { [class match [string tolower [HTTP::uri]] starts_with dc-uri-filter-dg] } {
        set local_var [class match -name [string tolower [HTTP::uri]] starts_with dc-uri-filter-dg]
        if { ( [string tolower [HTTP::uri]] equals $local_var ) or ( [string tolower [HTTP::uri]] starts_with "${local_var}/" ) } {
            SSL::disable serverside
            pool ACA-Pool_appl.com_http
        } else {
            HTTP::respond 200 content "Forbidden"
        }
    }   
}

where "dc-uri-filter-dg" is a string-based data group that contains the base URI. Example:

"/manorbon" := ""
"/foo" := ""
"/bar" := ""
"/test" := ""

The iRule will match only the defined base URI (equals) or the base URI plus a "/" (starts_with).
