www. and no www. - at the same time? (killed by base href!)

Just a thought . . . Evolution has a FURL prefix system setting (Revolution does not). You might be able to write a plugin that would modify it on the fly and set it to "" or "www." based on the URL the user came in through (maybe saved in a $_SESSION variable).

I also thought about something similar briefly. If only base href handled wildcards

I think a plugin playing on the Friendly URL system is going to be the best solution, because I don’t see how this can be solved on the server level while using base href. I know some php and js, but not enough to attempt this. The logic is fairly simple though, just parse the input URI, ’remember’ it - then toss it into the FURL output...

I think we are on the right track now haha
