The multiple PROPFIND commands should be done with the command line
client as well. It is part of the webdav protocol spec. (Basically a
client needs to "discover" things about the repository and this is done
with the propfind commands.) This is done somewhat inefficiently, but
that is all handled by the neon library which svn uses. You will also
notice that everything is usually tried twice as well. Once without any
authentication, then again with authentication, if it is needed.
For anyone interested in a nice (free) debugging web proxy on windows, I
suggest using fidder (http://www.fiddler2.com/fiddler2/). It can even
decode https traffic... You will need to reconfigure your svn proxy
settings to make this work. This is fairly easy, but I can provide more
details if needed.
BTW, there has been talk on the svn developers list about having an
alternate optimized http protocol not based upon webdav. This would
simplify the connection considerably.
