Apple

Thanks for everyone,

But maybe – if it works correct in 10.11, maybe there is any means to make it working in other versions of Mac OS?

Subject: Re: How SCNetworkReachability works with proxy and no DNS resolving?

In my code, I check whether the server’s address requires a proxy. If so, I use the reachability API only to check whether an Internet connection is available, and then try to connect.

Here’s the code I use to check for a proxy:

+ (BOOL) usingProxyForURL: (NSURL*)url {

NSDictionary* settings = CFBridgingRelease(CFNetworkCopySystemProxySettings());

NSArray* proxies = CFBridgingRelease(CFNetworkCopyProxiesForURL((__bridge CFURLRef)url,

(__bridge CFDictionaryRef)settings));

for (NSDictionary* proxy in proxies) {

if (![proxy[(id)kCFProxyTypeKey] isEqual: (id)kCFProxyTypeNone])

return YES;

}

return NO;

}
