How to redirect customer portal?

[Dominik Bauchner]

When a customer logs in, redirection brings him to: mysite.com/plugins/servlet/theme/portals/category/6 .

I would like to redirect customers directly to URL: mysite.com/plugins/servlet/theme/portal/10.

When I set reverse proxy redirection, it works only when I put URL mysite.com/plugins/servlet/theme/portals/category/6 to a web browser. Not automatically, when the user logs in. When users logs, redirection is not go to the reverse proxy. I there any way to set a kind of internal redirection?

@Dominik Bauchner I am not aware of a way to redirect the login page without modifying the code which I have not even researched where to do this at.  We got around this by creating a vanity url that redirected to the portal so when the use logs it it takes them to the correct location or if they are already logged it it took them to the correct place.  

Example:
vanity.mysite.com -> mysite.com/plugins/servlet/theme/portal/10
