Two main questions: (1) Does anybody *have* good documentation on VIRTUAL_URL and how it interacts with CookieCrumbler and VirtualHostMonster? (2) Does anyone know how to debug VirtualHostMonster or other Python libraries while running a Zope instance (it lives in Python not in Zope, so I don't know if I change the code there if those changes will actually get executed)?
For people who care to read more about what I think is going on: > Well, where is VIRTUAL_URL documented? Why doesn't Plohn do something > sane if it's not there? It's not Plone's issue from what I can tell. CookieCrumbler, which lives in CMF, does do something sane if VIRTUAL_URL is not there -- it tries to create a substitute URL. VIRTUAL_URL is set by the VirtualHostMonster. Does anyone know how to debug it? Because it is in the python directories used to build Zope, not in a Zope product which I know how to debug. (Is there a way to restart python to register changes in VirtualHostMonster.py)? Here is what I can tell of what is going on: (1) VIRTUAL_URL is supposed to return the actual URL when there is a Virtual Hosting Monster, for instance http://subdomain.mydomain.org instead of http://ip:port/path/to/subdomain/object or http://mydomain.org/path/to/subdomain/object. (2) There's an Apache rewrite rule set to transform URL requests like http://subdomain.org to http://ip:port/VirtualHostBase/http/subdomain.mydomain.org before they get sent into Zope. (3) When VirtualHostMonster receives a request like http://ip:port/VirtualHostBase/http/subdomain.mydomain.org, it is supposed to return the currect object at http://ip:port/path/to/subdomain/object and set a variable VIRTUAL_URL http://subdomain.mydomain.org in the REQUEST variable. (4) When navigating to an authenticated-only page, CMFCore's CookieCrumbler sets a "came_from" variable to remember where to go. To set the "came_from" variable, it first looks for VIRTUAL_URL. If it doesn't find it, it uses another method to set "came_from" -- but this returns an URL, and one that does not work. (5) During login in Plone to a authenticated-only page, it uses CMFCore's CookieCrumbler came_from variable. > > > I'm wondering if CookieCrumbler is supposed > > to set VIRTUAL_URL given that there's a VHM installed and doesn't? > > It's probably some code in the publisher or vhm.
