Thanks for the response, Lupo49.
Had a look at the link about the internal export function. My first impression with it was "Yes, but this is again For. Single. Pages." Then I noticed the last sentence on the page:
You can specify the do parameter as an HTTP header called X-DOKUWIKI-DO, too. This may be useful for creating a static dump with a website spider.
Now, I don't really know what that means, but, it appears to be something in the right direction.
Will look into it and report, since others have been asking about the same thing.
Any feedback is of course appreciated!
