I have a problem similar to the one described in ths SO question: http://stackoverflow.com/questions/2286586/mirror-svn-repository-write-through-proxying, but with more restrictive circumstances.
We are working along side a different development team who have the 'master' SVN repositry that they are using, we have access to this via VPN but would like to proxy this internally to a 'slave' repository. Workflow would be something like this:
- Copy from the 'master' repository to the 'slave' repository
- We work in the 'slave' repository until we are happy
- Check the changes back in from the 'slave' repository to the 'master' repository
So the 'slave' repository is essentially acting as a branch from the 'master' - we have full control over the 'slave' repository server, but want to avoid any changes to the 'master' server.
