Even use cookie is possible to make an mobile application, but the server should provide api to verify username and password and return cookie value for this session. And the mobile then set the cookie for following requests. I give it a sample for iOS platform. // set cookie storage NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; [cookieStorage setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways]; CDVPluginResult * result = nil; NSString *appUrl = [command.arguments objectAtIndex:0]; NSString *appCookie = [command.arguments objectAtIndex:1]; if (appUrl != nil && [appUrl length] > 0 && appCookie != nil && [appCookie length] > 0) { NSArray *cookieArray = [appCookie componentsSeparatedByString:@";"]; for (NSString *cookieItem in cookieArray) { NSMutableDictionary *cookieDict = [NSMutableDictionary dictionary]; NSRange range = [cookieItem rangeOfString:@"connect.sid="]; if (range.location != NSNotFound){ NSString *cookieValue = [cookieItem substringFromIndex:(range.location + range.length)]; //domainCookie = [cookieItem stringByAppendingString:domainRapidApps]; //[cookieDict setObject:domainCookie forKey:NSHTTPCookieValue]; NSURL *url = [NSURL URLWithString:[appUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSString *domain = [url host]; // set cookie [cookieDict setObject:@"connect.sid" forKey:NSHTTPCookieName]; [cookieDict setObject:cookieValue forKey:NSHTTPCookieValue]; [cookieDict setObject:domain forKey:NSHTTPCookieDomain]; [cookieDict setObject:@"/" forKey:NSHTTPCookiePath]; [cookieDict setObject:@"0" forKey:NSHTTPCookieVersion]; NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieDict]; [cookieStorage setCookie:cookie]; } }

@baris Yes I use Redis for NodeBB, so it gets applied to the integrated socket.io. But also it seems like I misinterpreted the problem for some reasons... Several features are not working with clustering, for example the chat: I can open it, but... [image: 0a3f135134.png] As you see in this screenshot, sometimes I get the messages and sometimes I don't. Or the plugins, I can initiate installation and nothing happens but the image changes. Installation through the ACP just don't work with clustering. I haven't tested it yet together with websockets, as I'm a cloudflare customer and haven't got access to the websockets right now.
