[Zope-dev] REQUEST.steps

[Evan Simpson]

REQUEST has a lot of standard attributes and keys, some of which are
obsolete.

Deprecated attributes:

o script: URL for the root object, computed from environment variables
including SCRIPT_NAME. Replace with REQUEST['BASE1'] or REQUEST['BASEPATH1']

o base: URL for level above root object, computed from same environment
variables as script. Replace with REQUEST['BASE0'] or REQUEST['BASEPATH0']

Unaffected by virtual hosting:

o steps: list of names traversed during publishing.

o PARENTS: list of objects traversed during publishing, including objects
added by __bobo_traverse__ hooks. The order of this list is reversed once
publishing is complete.

Virtual hosting-aware keys:

o URL: URL of current traversal target relative to VirtualRoot.

o URLn: URL with n path elements removed from the end.

o URLPATHn: URLn without SERVER_URL.

o BASEn: URL including only the first n-1 elements after the VirtualRoot.

o BASEPATHn: BASEn without SERVER_URL.

o SERVER_URL: URL of the server ('http://hostname:port')

Cheers,

Evan @ digicool & 4-am

o VirtualRootPhysicalPath: The physical path of the virtual root. Used to
compute absolute_url().
