How to expand irule using switch or logical or in selection process?

Developers want to add more "lanes" for multiple branches, so I want to add 3 more versions of "starts_with" and make the "if nots" more generic so they can apply to all the "starts_with" versions. ...

Hi,

you can try this irule:

when HTTP_REQUEST {
  set MY_HOST [string tolower [HTTP::host]]
  set MY_URI [string tolower [HTTP::uri]]
    switch -glob $MY_URI {
        "*/web/abcdpayment.web/*" -
        "*/web/abcdpaymentprocessing.web/*" {TCP::close}
        "/abcd/*" -
        "/abcd_lane2/*" -
        "/abcd_hotfix/*" {
            switch $MY_HOST {
                "m3.corpname.com" {HTTP::redirect http://a1.m3.corpname.com$MY_URI}
                "intra.m3.corpname.com" {HTTP::redirect http://intra.a1.m3.corpname.com$MY_URI}
                "intra.m3-dc1.corpname.com" {HTTP::redirect http://intra.a1.m3-dc1.corpname.com$MY_URI}
                "intra.m3-dc2.corpname.com" {HTTP::redirect http://intra.a1.m3-dc2.corpname.com$MY_URI}
                "intra.m3-dc3.corpname.com" {HTTP::redirect http://intra.a1.m3-dc3.corpname.com$MY_URI}   
            }
        TCP::close
        }
    }
}
