Probs with rewrite redirects

[Markus Klaffke]

I have a problem with mod-rewrite rules. My blog software generates its content this way:
If a request for a website comes in, first a gateway.cgi script in /python-cms must be asked if the requested html page exists in the cache folder (/blog) or not. If it exists, the page will be fetched from the cache, if not it will be generated and saved in /blog. Thus the way is /blog and if nothing is found it goes to /python-cms/gateway.cgi. But The redirect to /python-cms/gateway.cgi doesn' t work.

1. Calling http://example.com should redirect me to http://example.com/blog or if there is no cached index.html, it should redirect me to http://example.com/python-cms/gateway.cgi to generate the missing index.html. But the result is now the index view of http://example.com.

2. If there is no index.html in /blog: Calling http://example.com/blog/ gives me the index view of /blog and does not redirect to /python-cms/gateway.cgi.

Above is my complete .htaccess file. It is very long, but maybe someone of the boards experts find the time to check it. If there are other errors or stuff that can be written better or is not needed, please let me know. Thansk in advance.
