----------------------------------
Did a few tracers (it certainly seems a lot more difficult to reproduce this
with tracers on, so perhaps a race / timing issue). First is request that

> I wouldn't submit this bug in the first place, if it didn't work with Squid
> either. Alas Squid passes with flying colours! Attatched you can find
> wireshark captures for the four scenarios:
> * Failure with ATS (old subversion server: sf.net)
> * Success with Squid (same old subversion server: sf.net)
> * Success with ATS (new Subversion server: ASF)
> * Success with Squid (same new Subversion server: ASF)
> To force subversion through a proxy you need to edit ~/.subversion/servers
