wpf - Signalr Balanced environment 500 Internal server error -


i'm experiencing problems installing signalr app on balanced environment

my scenario : wpf app -> f5 balancer -> services hosted on iis 7 win 2008 r2. no backplane configuration, app server client ticker, server communicate connected clients

i read lot around forums:

i've configured machine key on servers i've configured server traces (no files created on web app folder) signalr ping works (http:<mydomain>:8081/signar/ping) signalr hubs shown (httpd:<mydomain>:8081/signar/hubs)

every time client start connecting see fiddler : 

http://<mydomain>:8081/signalr/negotiate?clientprotocol=1.4&connectiondata=%5b%7b%22name%22:%22agentshub%22%7d%5d

i : 

http/1.1 500 internal server error content-length: 0 server: microsoft-httpapi/2.0 date: thu, 14 may 2015 09:57:54 gmt

port 8081 opened, signalr ping replies me, on laptop scenario works.

i don't know how solve it.

any suggestions ?

many thanks

i've found wrong in configuration.

1) started develop example app wpf client , console .net self host signalr, using signalr documentation bootstrap option, self host apps : webapp.start(config.getsignalrserveruri);.

2) i've added new asp.net service, using same bootstrap method, forgetting install nuget aspnet.signalr package.

service replying ping , hubs rest services replying, connection pipeline wasn't working.

3) removing webapp.start(config.getsignalrserveruri) , using startup class: 

[assembly: owinstartup(typeof(startup))] namespace myapp.host.webservice.signalr {     public class startup     {         private static readonly ilog log = logmanager.getlogger(typeof(startup));          public void configuration(iappbuilder app)         {             // connection or hub wire , configuration should go here             try             {                  var hubconfiguration = new hubconfiguration();                 hubconfiguration.enabledetailederrors = true;                 app.mapsignalr("/signalr",hubconfiguration);                 log.debug("signalr started");             }             catch (exception ex)             {                 log.error("error during signalr startup");                 log.error(ex);             }         }     } }

and including microsoft.signalr package, working.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
