If your introduction to object-oriented programming was like mine, somewhere early on day 1 you learned about “message passing.” You were told that doing something like

    account.deposit(50)

meant that you were sending the deposit message to the account object. Of course, if you were learning about a statically typed language, you soon figured out that account.deposit(50) was synonymous with calling the deposit method on the account object. The whole static typing system was there to make sure that the deposit method was there and was called. So by the end of day 1 of object-oriented programming, we all stopped talking about passing messages and started talking about calling methods.
The concept of message passing would make more sense if we could say account.deposit(50), and the BankAccount class was then free to do something else with the message besides simply calling the deposit method. Perhaps the BankAccount class could call some method other than deposit, or perhaps it could decide to do nothing. I

#
# CORS header support
#
# One way to use this is by placing it into a file called "cors_support"
# under your Nginx configuration directory and placing the following
# statement inside your location block(s):
#
#   include cors_support;
#
# A limitation to this method is that Nginx doesn't currently send headers
