I hawe two sets of websides :

2 : https://www.aaa.com/cms/

3 : http://aaa.com

4 : https://aaa.com

http://www.aaa.com : this one have a iroute redirecting if the urls contains "/cms" to https://www.aaa.com/cms/ (works fine)

but if an user writes https://www.aaa.com we wants it to redirect to https://aaa.com

I have tryed with this one :

when HTTP_REQUEST {

if { [HTTP::uri] ends_with "/cms/" }{

pool web-node

} else {

HTTP::redirect "https://aaa.com"

}

}

but the browser comes up with an cert error (getting the cert for https://aaa.com)
