Target release: 3.x
LinguaPlone version: 3.0.
Environment: Plone 3.3.2, CMF 2.1.2, Zope 2.10.7-final, Python 2.4.5.

The problem with LinguaPlone language selector links, when the Plone site is behind behind Apache and Virtual Host Monster, was previously reported by Hanno Schlichting (bug #216, http://plone.org/products/linguaplone/issues/216): language selector ("flags") link urls contained ".../VirtualHostBase/http/...".

The bug was reported as fixed in version 3.0.b8, but in some circumstances it appears in version 3.0, namely when a folder is used as a default page view item for the portal root, and the default page view item for that folder is also selected. When the default page view item for the portal root is a page, language selector links work fine.
Steps to reproduce:
0. Create Plone site with LinguaPlone (my versions were Plone 3.3.2 and LinguaPlone 3.0) with two or more portal languages selected - let them be English and Russian. Create Apache redirect to the site through the VirtualHostBase.
1. At the portal root create the folder '/en' in English and translate it into folder '/ru' in Russian.
2. In folder '/en' create som page 'test' in English and translate it into '/ru/test' in Russian.
3. Make '/en/test' be a default page view item for the folder '/en', and make '/ru/test' a default page for '/ru'.
4. Make 'Folder' content type available to be selected as a default page view item: add 'Folder' line to default_page_types lines field at /portal_properties/site properties through the ZMI.
5. Make '/en' folder be a default page view item for the portal root.

Now, when you view the portal root, language selector link urls will contain VHM stuff like '.../VirtualHostBase/http/...' and, naturally, won't work. When you go to some page at the portal, links will become correct.

The problem was actually not in default view, but in the Virtual Host Monster path elements and the way LinguaPlone 3.0 tries to ignore them. It ignores '/VirtualHostRoot/' but not '/VirtualHostBase/.../.../'.

Here's a patch I used:
> if 'VirtualHostBase' in current_path:
> while current_path[-1] != 'VirtualHostBase':
> current_path.pop()
> current_path.pop() # remove 'VirtualHostBase' itself

Whitespaces disappeared. One more attempt. Initial underscores should be replaced with spaces.
>_________________if 'VirtualHostBase' in current_path:

>_____________________current_path.pop() # remove 'VirtualHostBase' itself

A possible fix might also be:

and, yes - I can confirm the bug for a site where folders were enabled as default view of other folders and it feels there needs to be a '4' in case one carries on the idea...

I currently don't have an opinion whether folders as default views of folders are good or bad, but it seems to be possible to set it up.

I visited several web pages but the audio feature for audio songs existing at this web site is actually wonderful.
