nope. I just checked sources for debian package 3.0.9-1.
I found two different ways of checking the proxy settings. The first one
uses all environment variable, the second one use gconf.
If using env vars, the problem is in file
toolkit/system/unixproxy/nsUnixSystemProxySettings.cpp, function
IsInNoProxyList(...) where this comparison is used:
if (port == -1 || port == aPort) {
nsDependentCSubstring hostStr(pos, colon);
// By using StringEndsWith instead of an equality comparator, we can
include sub-domains
if (StringEndsWith(aHost, hostStr, nsCaseInsensitiveCStringComparator()))
return PR_TRUE;
}
so, since this is a string comparison, this is not working for CIDR.
I don't know why it is using the proxy for http://127.0.0.1/ when
no_proxy is just 127.0.0.1. Maybe the proxy
If using gconf, as I think it is my case, is uses *GConf* functions in
the same source. In this case it accept exclusion lists like
hostname
ipv4address
CIDR
*.domain.tld
To check for CIDR, it convert both addresses (the proxy specified one
and the url) to ipv6 and then it use memcmp.
I do believe, it uses gconf, since this command still get the page via
proxy:
$ env no_proxy= http_proxy= iceweasel http://127.0.0.1/
my proxy setting, via gconf, are:
$ for i in /system/proxy/mode /system/proxy/autoconfig_url \
/system/http_proxy/use_http_proxy \
/system/http_proxy/ignore_hosts \
/system/http_proxy/use_same_proxy ;
do echo -n $i:; gconftool-2 --get $i; done
/system/proxy/mode:manual
/system/proxy/autoconfig_url:
/system/http_proxy/use_http_proxy:true
/system/http_proxy/ignore_hosts:[localhost,127.0.0.0/8,192.168.0.0/16,scarafaggio]
/system/http_proxy/use_same_proxy:true
Bye,
Giuseppe
