Handle request with .gsp in URL In Grails 6.2.3, I have to handle request with .gsp extension like http://localhost:8080/report/view.gsp?a=b I can't map this URL to controller, action. It will always return error 404. I test URL with many other extensions and they are all work without any modification to UrlMappings.groovy. For example http://localhost:8080/report/view.gspx?a=b http://localhost:8080/report/view.abc http://localhost:8080/report/view.xyz This question suggests it should work, but it from Grails-3.3. <a...
