Description

When trying to access older Subversion (1.6.9, 1.5.1 verified) servers through SSL via the Forward proxy, I'll get a failure such as:

igalic@knock ~/src % svn co https://gar.svn.sourceforge.net/svnroot/gar/csw/mgar/gar/
svn: PROPFIND of '/svnroot/gar/!svn/bln/14844': Could not create SSL connection through proxy server: 502 Tunnel Connection Failed (https://gar.svn.sourceforge.net)

While the error log says:

With newer versions of the Subversion server this works out fine, example the ASF's server:

igalic@knock ~/src % svn co https://svn.apache.org/repos/asf/trafficserver/plugins/header_filter/
A    header_filter/example.conf
A    header_filter/rules.h
A    header_filter/NOTICE
A    header_filter/header_filter.cc
A    header_filter/LICENSE
A    header_filter/STATUS
A    header_filter/lulu.h
A    header_filter/CHANGES
A    header_filter/Makefile
A    header_filter/README
A    header_filter/rules.cc
Checked out revision 1137808.

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

[global]
http-proxy-host = localhost
http-proxy-port = 8080
