The lock model we have discussed todate requires that lock tokens be distributed across the entire network and that lock token validation be performed before some methods are executed. I don't think that cross server locks are "FAR FAR FAR" into the future, they are very close. -src >>> Yaron Goland <yarong@microsoft.com> 03/24/97 06:23PM >>> The problem is that e-tags are opaque and we really need to be able to put lock tokens into if-match headers. Are we going to be forced to invent our own "if-match" header for lock tokens or can we extend the if-match syntax to accept tokens? My feeling is that lock tokens should be URIs (this also gives the possibility of having cross server locks on day, FAR FAR FAR into the future =) and that we should extend the e-tag if headers to accept tokens instead of just quoted strings.
