Generate Web Pages
Use this option to enable and disable the production of start up web pages while doing development.
If you have 10 languages defined then when you save your Framework pages will be generated for all 10 languages and then copied to your HTTP server.
This can be a time consuming process, so you can selectively disable language(s) while you are developing and testing to reduce this time. When you have completed your development cycle you can then (re)enable them to produce final copies of all the HTML start up pages ready for deployment.
This property is in the Web/RAMP Details tab.
