"clean urls" in pier

Hi, One of the thing I'm missing with Pier is "clean urls" -- without the session stuff. I played with the code a bit, followed advices from http://onsmalltalk.com/clean-urls-in-seaside to get rid of _s, and then modifyed the visitInternalLink in PRReferenceRenderer so that links do not include _k. I simply do something like that: anchor url: 'http://localhost:8080/seaside/pier', aLink reference which sets the url fully, and apparently everything seems to work as hoped -- links indicated in pier are now fully formed and without _s and _k, while dynamically generated links still work so for example I can still log in and edit pages as usual... but in "normal viewing mode" I get clean urls. My question is, am I breaking something I'm not seeing (as apparently things works as I want) by doing that ? is that the correct way to do it ? thanks, -- Nicolas Roard "I love deadlines.
