I think the question says it all. I am using a server that exposes an svn repository through HTML, and am wondering if I can specify a previous revision of files when linking to it. I believe the server uses Apache and mod_dav, but am not sure as I don't administer it.
Here's an old thread on the SVN mailing list asking a similar question. Tacking on the
!svn/bc/###/ bit seems to work on one repo I have access to, but it seems it's implementation-specific.
