Subversion and IPCop

In the default configuration, IPCop’s transparent proxy does not allow subversion to work (when using WebDAV–ssh would be fine of course).

Although the squid proxy supports WebDAV, subversion uses some non-standard methods that squid blocks.

For example, trying to check out a module fails:

svn: REPORT request failed on '/svn/mojain/!svn/vcc/default'
svn: REPORT of '/svn/mojain/!svn/vcc/default': 400 Bad Request (http://...)

Adding the following lines to squid.conf (which on IPCop 1.4.6 is located at /etc/squid/squid.conf) allows svn to work:

extension_methods request REPORT
extension_methods request MKACTIVITY
extension_methods request CHECKOUT
extension_methods request MERGE

You need to restart squid for this to take effect:
