Dear All: I'm interested in subversion and i want to know how the client communicate with the subversion based on apache web server.I use wireshark to get the package when check-out a directory in the server ,and find that after a options method with authorization there are many propfind methods,and many URL in the propfind command line is the same,i can't understand,if you want to get the specific version's URL,just use: 1).Fetch the following properties from the given URL DAV:version-controlled-configuration svn:baseline-relative-path DAV:resourcetype 2). Fetch the DAV:checked-in and a Label header from the VCC(we got it in the step 1),it points to the Baseline
3).From the Baseline, we fetch the following properties: DAV:baseline-collection DAV:version-name and the href in DAV:baseline-collection is the URL we need. So,in my opinion,three propfind is enough to checkout a directory. But the fact is,the client create two TCP connection,and in every connection client will repeat the 3 steps.I can't find doc to declare the principle,wish a reply that can release my doubts. Thanks.
