Bypass SSL redirect if URI is....

I have 2 set of iRules that I'd like to combine into 1, however I'm unable to apply the logic without the result ending up in a loop.

The end result needs to be - if the URI is "/articles/2015/09/09/something.aspx" then allow the rest over port 80, else redirect to HTTPS. Always strip the www from the hostname as well.

I've only been able to get this to work on the iRule that I've applied on the port 443 VIP. I removed similar logic to check if the hostname begins with www, as it resulted in a loop. I'd like to be able to have 1 iRule that I could apply to both VIP-80 and VIP-443, however having 2 separate iRules is not a dealbreaker.

iRule applied to VIP-80:

when HTTP_REQUEST {
    if { [string tolower [HTTP::uri]] starts_with "/articles/2015/09/09/something.aspx" } {
       allow the request
      return 
    } else {
       HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
    }
}

iRule applied to VIP-443:

when HTTP_REQUEST {
    if { [string tolower [HTTP::uri]] starts_with "/articles/2015/09/09/something.aspx" } {
        HTTP::redirect http://[getfield [HTTP::host] ":" 1][HTTP::uri]
    } else {
        allow the request
       return
    }
}
