Apache - url redirect from Subfolder url to https.

Good Morning,

im no linux guru but would like some help.

we have a website.   www.test.com

there is a sub folder containing access to staff login page.  

http:\\test.com\staff\

I have now set this up with a ssl certificate so now we have

https:\\staff.test.com

I need to either block access directly to the url http:\\test.com\staff\

or redirect back to https:\\staff.test.com  (which ever is easiest  )

I tried a Virtualhost entry in my apache config file but it doesnt seem to like the subfolder.  (I also need to redirect  http:\\staff.test.com to https:\\staff.test.com  this bit seems to be working details below)

I tried this:

# the one needs to redirect  http://test.com/staff   to https://staff.test.com - not working?

<VirtualHost *:80>
  ServerName www.test.com/staff
  ServerAlias https://staff.test.com  http://test.com/staff
  Redirect / https://staff.test.com/
</VirtualHost>

#This one below works - it redirect http://staff.test.com to https://staff.test.com

<VirtualHost *:80>
  ServerName http://staff.test.com
  ServerAlias https://staff.test.com http://staff.test.com
  Redirect / https://staff.test.com/
</VirtualHost>


Any help would be appeciated...
