At a customer's site I need to serve different Zope instances from virtual subdirectories. www.dom.com/f1/ -> z1.dom.com/ www.dom.com/f2/ -> z2.dom.com/ ... However I am out of luck with VHM. The following works only partially: RewriteRule ^/f1/(.*) \ http://z1:8080/VirtualHostBase/http/www.dom.com:80/VirtualHostRoot/_vh_f1/$1 It appears that I cannot serve the Zope root folder with this technique. What I get are locations starting with double slashes ('//'), confusing the hell out of my browsers. I *can* serve subfolders but that is not what I want. From the docs it seems that it should work so it might very well be a bug. Note that it works with a static SiteRoot object configured like Base: http://www.dom.com Path: /f1 But that is also not what I want because the host and protocol parts are actually dynamic (passed to Apache in some custom HTTP headers). Any hints appreciated, Stefan -- Those who write software only for pay should go hurt some other field. /Erik Naggum/
