iRule Streams how to maintain / stream line.

Hey Folks,

I have the following code that is getting bigger and bigger, and just wondering if there is a more efficient way to maintain the list that is use the streams re-write.

Code    if { [HTTP::header value Content-Type] contains "text"} {
    STREAM::expression "@appdev:9080@appdev@ @appdev.fqdn.name:9080@appdev.fqdn.name@ @appconfig:9180@appconfigconfig@ @appconfig.fqdn.name:9180@appconfig.fqdn.name@ @appmaster:9170@appmaster@ @appmaster.fqdn.name:9170@appmaster.fqdn.name@ @appcustom:9190@appcustom@ @appconfig.fqdn.name:9190@appconfig.fqdn.name@"
    STREAM::enable
}

Thoughts, opinions?
