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;
}
