I know that port 443 normally is used for https connections. Nevertheless I experience a difference in HFS's reaction when using port 443 instead of port numbers like 80 or 8080.
I have a root with a number of virtual maps (for each user a virtual map). Within the virtual map I use other virtual maps or I attach real system directories.
Now when I browse using port 443 then I can access a user's virtual map in the HFS's root. It then shows a listing of the attached sub maps. However if I click on one of these submaps then I get an 404 HTML error page.
However when I switch to using another port like 8080 then I do not get these 404's and I am able to surf to all submaps at any level.
Is there an explanation for this?
