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

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.
