Crawling with a url key / cookie

Thank you for developing FESS. I think it is an awesome project!

I have an internal website I want to crawl/index. It is protected by a key in the query string on first access. Like this:

After loading the first page with the key two cookies are set: cookie1 and cookie2. Subsequent urls can then be loaded if the cookies are present (the site links no longer contains the key).

How can I make sure FESS can crawl the website? Can I append the ?key=abc123 to all URL:s in some way? Can I make FESS remember the cookies after the first page access?

You might be able to use Path Mapping with Stored URLs as Process Type.
Fess Crawler keeps session information on the same crawling config.
