Disable Keep Alives and/or Pipelining?

We run through a reverse proxy for SVN access and that proxy has
KeepAlives disabled, as a result, I've been asked if it's possible to
disable KeepAlives and/or HTTP Pipelining in the subversion client?

For some background, we are getting SSL errors when trying to checkout /
update that don't occur going to the server direct (bypassing the proxy)
and all we see in the reverse proxy (Apache HTTPd under the covers) logs
are:

     "insecure re-negotiation required, but a pipelined request is
present; keep alive disabled"

TortoiseSVN returns:

     Error running context: An error occurred during SSL communication

The SVN Server (CollabNET) -

     Reports a broken pipe, with a "HINT: Stop button pressed in
browser?" type message

Thanks in advance,
