Hi, without knowing your actual requirements. What about if you use simpleaddress with relaxed language routing?
Old blog post by Johan Björnfot, I've posted an update to that blog posting, how to get it to work in CMS 10.x+
I've used that to have simple addresses without language segment in multi-language sites.
I have configured the site so that it always includes language segment in the URL by configuring the site without primary language. Now it always includes language segment except for the start page.
Now I need one page to be served without language segment. It should default to English in my case. Is there any way to achieve it?
