[Toolserver-announce] change of regular expression behaviour in rewrite scripts

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, after the web server change on Wednesday, we noticed the following behaviour of regexp matching in rewrite scripts: when using a construct like "(a|b|)", the regexp will *not* match the empty string. as a workaround, you can write "(a|b)?". if you do not use this construct in your rewrite.script, this does not affect you. we have raised this issue with Zeus and are waiting for a resolution. - river.
