RE: Mirroring with Webdav-proxy

Thank you, Erik.

I read the documentation you gave, but I still have a pair of questions :
* If the master is modified while one of the slave is unreachable, they will be de-synchronized. I don't know hooks very well, but I think they cannot be set on read operations… Is there a way to re-synchronize the slave when connection is retrieved and slave recieves a read query (not sure I'm clear) ?
* Do you have an idea (even aproximative) of when version 1.5 will be released ?

Thanks again…
