Cleaning FastCGI cache automatically?

Hi all,

I've been reading about NGINX lately and ran into the following 'issues'. It seems that caching with FastCGI does not support automatic cache purges ?

For example :

1. I would like to be able to upload static pages through Filezilla into a certain directory and have the cache update itself immediately (and automatically). I need updates of static content to be reflected immediately in the cache...
2. I would like to use FastCGI to cache Wordpress files and have the cache update itself immediately after a content update.

Does anyone know if there is a way to accomplish the above requirements ? Is this really not possible with default NGINX ? Maybe there's a way to do it with EasyEngine ?

Thanks in advance, Lex
