Mongrel behin Apache proxy: get "permission denied"

I am trying to run a Typo app behind on mongrel, with Apache proxying on
Windows XP. The idea is to have the subdirectory /ebway point to my app.
I am using the following code in my http.conf:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
ProxyRequests Off

<Proxy *>
	Order deny,allow
	Allow from all
</Proxy>


Alias /ebway "c:/mongrel/ebway/public"

<Directory "c:/mongrel/ebway/public">
	Options Indexes FollowSymLinks
	AllowOverride none
	Order allow,deny
	Allow from all
</Directory>

ProxyPass /ebway/ http://127.0.0.1:4000/

ProxyPass /ebway http://127.0.0.1:4000/
ProxyPassReverse /ebway/ http://127.0.0.1:4000/

Which works for .html files and the rest of the app, but if I try to
access images or .css files I get “permission denied” errors.

(I have set the base url of the app, that shouldn’t be the problem)

I came up with the answer myself, I’ll share it, since I haven’t got any
replies:

Typo uses files from directories other than public as well, simply
change

<Directory “c:/mongrel/ebway/public”>
Options Indexes FollowSymLinks
AllowOverride none
Order allow,deny
Allow from all

to

<Directory “c:/mongrel/ebway”>
Options Indexes FollowSymLinks
AllowOverride none
Order allow,deny
Allow from all

and it should work.
