Subject [Subversion Wiki] Update of "ServerDictatedConfiguration" by CMichaelPilato

Dear Wiki user,

The "ServerDictatedConfiguration" page has been changed by CMichaelPilato:
http://wiki.apache.org/subversion/ServerDictatedConfiguration?action=diff&rev1=9&rev2=10

  
  === Server-client transmission mechanism ===
  
- As part of the OPTIONS request, the client will send to the server the sha1 hash of the
version of the server-dictated config that it current has cached.  If the server has a different
version, it will send that to the client in the OPTIONS response.
+ Over ra-neon/ra-serf, the client will send to the server the sha1 hash of the server-dictated
config that it current has cached as part of the OPTIONS request.  If the server has a different
version, it will send that to the client in the OPTIONS response.  For ra-svn, a similar thing
happens as part of the initial connection handshake/feature exchange.  This is an opportunistic
caching approach, keeping the client in sync with the repository configuration any time the
client contacts the repository.  This mechanism requires that there exist a predictable and
consistent manner in which to calculate the checksum of the configuration.
  
  === Server-side storage ===
