Gideon So Posted November 30, 2016 Share Posted November 30, 2016 Hi, I found that it is not possible to insert a link with underscore in the sub-domain part of a url, for example, my_sundomain.mydomain.com. Once save the page the link becomes "/". Is it intentional or a bug?? Gideon Link to comment Share on other sites More sharing options...
BitPoet Posted November 30, 2016 Share Posted November 30, 2016 Underscores in host names are invalid according to RFC1132, which allows only letters, digits and hyphens. They are only allowed in DNS names for resource records. So PW is operating in undefined territory. 3 Link to comment Share on other sites More sharing options...
