I'm accessing an external repository linked via svn:externals, say this external URL is https://subversion.example.com/rootpath/myproj
When I checkout a dir from my own repository, the external reference is retrieved fine. If I change the svn:externals to another revision (the path is the same) and run "svn update", I get this error: svn: warning: Server sent unexpected return value (403 Forbidden) in response to OPTIONS request for 'https://subversion.example.com/ rootpath' But if I delete the external directory and update again, everything comes fine. I really don't have permission to this root path, but I don't understand why it is necessary for an update and not necessary for an complete checkout. The client is version 1.6.9 and the server is version 1.6.3
