Re: [wildfly-dev] HTTP/2 out of the box in Wildfly 10.1

So while implementing this I have noticed a potential problem that it would be good to get some feedback on. If the management interface has SSL by default then the HTTP interface will always redirect to the HTTPS interface. This effectively breaks the management API, as clients such as the CLI, Arquillian etc will be redirected to HTTPS, and then reject the self signed certificate (as they should). I am not sure what to do about this, these are the options as I see them: 1) Don't enable SSL for the management interface (just for the Undertow subsystem). The management interface can still use this auto-generation capability, it just won't be enable by default (we could even leave the cert in the security domain, but just not enable the https interface). 2) Disable automatic redirects for HTTP upgrade requests (potentially controlled by an attribute). This will allow the CLI etc to work, but at the price of potentially reducing security, as some connections that would have previously been redirected to use HTTPS will no longer do this. 3) Enable it by default and leave it broken. We can setup some kind of automatic trust store thing so the local CLI works, and can get our test suite to work with Arquillian in a similar manner. Personally I think this is a terrible idea, but I am including it for completeness. Personally I think we should go for 1). Given that this is supposed to be about developer usability I don't think having management also use SSL as being that important. Stuart On Mon, Jun 6, 2016 at 10:24 PM, Jason T.

Another idea I had on how we could get away with it being in server boot, is to have a pre-boot first time setup task, either launched from the shell/batch scripts or as a special pre-step before the AS module loads. We could then report boot time as the time AFTER first time installation tasks have completed, which I think is fair because the server hasn't yet been started.
