[undertow-dev] Undertow development mode

Hi, In Wildfly upstream I am introducing a 'development mode' flag (it is actually in Alpha3 as well, but I am going to change how it is represented in the model). Basically the idea with this is that when this flag is set the server behaves in a way that is much more developer friendly, but is not suitable for production use. So far the changes are: - Set JSP development mode - Display stack traces in error pages. We do not do this by default for security reasons. - Disable caching so file changes are picked up straight away - Optionally persist session information across redeployments (still needs a little bit of work), which should prevent a developer from having to re-log in every time they redeploy. I was wondering if anyone had any ideas for other features we could add to make development easier? Stuart
