We have liferay 6.1-ga2 serving a main site and several subsites. In the protal settings we set /home as standard homepage, logout-page and root-url.
Now if we navigate to a subpage /web/projectFoo and then want to return the main-site by clicking the link in the breadcrumb or manually typing http://example.com/ (where example.com is of course replaced by our domain), we are not redirected to our standard-landing-page, but again to the last visited project.
If we explicitly type http://example.com/home, we reach our landing-page. But in the bread-crumb-line, the link points to /. And if we replace it via javascript with /home, there are still external links, that might point to http://example.com/ (in another tab ...)
How can we prevent this?
Now we fixed it. The problem was a wrong configuration in the site-settings:
The Home URL was missing a part of the path to the site:
/home is not enough, it has to be /web/guest/home, if /web/guest/ is the internal prefix for the site.
