Help with iRule

Good day all! I have the following iRule: when HTTP_REQUEST { if { ([HTTP::host] eq "lists.example.com") and ([HTTP::uri] eq "/cgi-bin/wa?INDEX" || [HTTP::uri] eq "/cgi-bin/wa?MOD" || [HTTP::uri...

You can negate that second IF as well to avoid the else

when HTTP_REQUEST priority 500 {
    if { (![class match -- [IP::client_addr] eq "LISTSERV-TST_Allowed_IPs"]) &&
         !(([HTTP::host] eq "lists.example.com") && ([HTTP::uri] matches_glob "/cgi-bin/wa?SUBEDIT1*")) } {
        HTTP::redirect "https://www.google.com"
    }
}

Would something like this work?

when HTTP_REQUEST priority 500 {
    if { ([HTTP::host] eq "lists.example.com") && ([HTTP::uri] matches_glob "/cgi-bin/wa?SUBEDIT1*") } { 
      return 
    } else {
            HTTP::redirect "https://www.google.com"    
    }
    if { [class match -- [IP::client_addr] eq "LISTSERV-TST_Allowed_IPs"] } {
      return
    }
}

Or this, rather:

when HTTP_REQUEST priority 500 {
  if { ![class match -- [IP::client_addr] eq "LISTSERV-TST_Allowed_IPs"] } {
    if { ([HTTP::host] eq "lists.example.com") && ([HTTP::uri] matches_glob "/cgi-bin/wa?SUBEDIT1*") } { 
          return 
    } else {
          HTTP::redirect "https://www.google.com"
    }
  }
}

I know we are close, so I am not certain on how to "wrap it up". 😅

  Did you miss the ! on `!([HTTP::uri]...`?

    looks like I just put it in the wrong place! Updated above.

  JRahmso, this is "working":
  when HTTP_REQUEST priority 500 { if { (![class match -- [IP::client_addr] eq "LISTSERV-TST_Allowed_IPs"]) && (([HTTP::host] eq "lists.example.com") && !([HTTP::uri] matches_glob "/cgi-bin/wa?SUBEDIT1*")) } { HTTP::redirect "https://www.google.com" } }
  But images are all broken. It is creating a weird CORS/redirect problem

    might be either a missing use case or the logic is slightly off. If use add the else back in and add return to that block does it fix?
