> There are several problems with using SOCKS. I am interested in case when TF 
> is sock client. Client sends HTTP request and TF uses SOCKS server to make 
> connection to internet.
> a/ - not documented enough in default configs
> From default configs comments it seems that for running 
> TF 4.1.2 as socks client, it is sufficient to add one line to socks.config:
> dest_ip=0.0.0.0-255.255.255.255 parent="10.0.0.7:9050"
> but socks proxy is not used. If i run tcpdump sniffing packets  TF never 
> tries to connect to that SOCKS.
> From source code - 
> https://github.com/apache/trafficserver/blob/master/iocore/net/Socks.cc it 
> looks that is needed to set "proxy.config.socks.socks_needed" to activate 
> socks support. This should be documented in both sample files: socks.config 
> and record.config
> b/
> after enabling socks, i am hit by this assert:
> Assertion failed: (ats_is_ip4(&target_addr)), function init, file Socks.cc, 
> line 65.
> i run on dual stack system (ip4,ip6). 
> This code is setting default destination for SOCKS request? Can not you use 
> just 127.0.0.1 for case if client gets connected over IP6?
