This is the main url->function dispatching data struct.

In short, it's a struct with various URLs plus their handlers. The handlers can
|
|
be 'standard' CGI functions you wrote, or 'special' CGIs requiring an argument.
|
|
They can also be auth-functions. An asterisk will match any url starting with
|
|
everything before the asterisks; "*" matches everything. The list will be
|
|
handled top-down, so make sure to put more specific rules above the more
|
|
general ones. Authorization things (like authBasic) act as a 'barrier' and
|
|
should be placed above the URLs they protect.
