Answer 1

So I found this known bug with VirtualBox VM that is used for running Docker on Mac. When we have shared content between our host machine and the VirtualBox, then only we face this bug. There is a optimisation as far as web servers like nginx, apache (and apparently vertx) are concerned. Whenever we request a static file from the server, it uses sendfile to provide us with the file. The bug is that in case of VirtualBox (in the scenario described above) we always get the first version of the file no matter what we try. The workaround for this in case of nginx and apache is to turn sendfile off . However, there is a hack that we use as far as vertx is concerned.

1. rename the file say login.html to login.html.moved (anything)
2. curl :/….../login.html (we won’t get anything)
3. rename the file back to its original name login.html.moved to login.html
4. Hard refresh the page (Command + Shift + R).
