## #Path specification format
|
|
##
|
|
## Path specification is written as standard path:
|
|
## *path_spec*[?*query_spec*]
|
|
## Where:
|
|
## *path_spec* is standard HTTP path separated with */* and following special
|
|
## characters:
|
|
## **@** - Required path component, it is captured as positional argument
|
|
## **@+** - Required path component, capture current and all subsequent
|
|
## components as path. Path is positional argument.
|
|
## *query_spec* is optional and allows for matching values of query arguments
|
|
## or transforming query arguments into positional arguments. It is written
|
|
## in form "?arg1=valueDef&arg2=valueDef"
|
|
## Following special characters are supported:
|
|
## **@** - Required argument, capture value as positional argument.
|
|
## **?@** - Optional argument, capture value as positional argument.
|
