The company I work for is currently using the UltiDev Cassini web server as an intranet web server. We have found that when using the two most recent versions of UltiDev Cassini, we are unable to restart the service successfully, consistently. Several times, the service will appear to have restarted successfully, but we are unable to access any web pages via the web server other than the admin page (http://localhost:7756). We have reproduced this behavior on a clean install of Windows XP Professional with only a basic html file as the page to be served. We created a test application that starts the service, attempts to access the test html page, then stops the service and tries again. We are starting and stopping the service using net start and net stop. Intermittently, this test fails, but a subsequent restart of the service seems to resolve the problem. This has been problematic for us in our production environments where frequent updates to content require stopping and starting the Cassini service. I greatly appreciate any assistance you can provide on resolving this matter.

We do not have any entries in the application log for UltiDev Cassini. We have to restart the service because we are replacing files that the web server has open. The files cannot be changed while a process has them open.

We encountered similar situation. We use UltiDev Cassini 2.0

Our scenario is:
1. we stop UltiDev Cassini service (this is done via ServiceController - c# API) by a process with SYSTEM privileges (a process run by user SYSTEM)
2. we start UltiDev Cassini service (this is done via ServiceController too) by a process with SYSTEM privileges
3. UltiDev Cassini windows service restarts succesfully - the service status is RUNNING,

but we are unable to access any web pages via the web server, even the admin page (http://localhost:7756)!

Surprisingly, the same scenario executed by a process with admin privileges (run by admin user) succeeds.

I browse my windows event log and I see a lots of errors:

first is information about successfully started Cassini service,
next two logs are errors:

original message (in polish):
Exception in Cassini web application [7756, "UltiDev Cassini Web Server Explorer"].
Exception:
System.Net.Sockets.SocketException: Tylko jedno użycie każdego adresu gniazda (protokół/adres sieciowy/port) jest normalnie dozwolone
w System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)
w System.Net.Sockets.Socket.Bind(EndPoint localEP)
w Cassini.Server.Start()
w CassiniService.Service1.WebAppEntry.Start()

in english is something like that:
Exception in Cassini web application [7756, "UltiDev Cassini Web Server Explorer"].
Exception:
System.Net.Sockets.SocketException: Only one use of each socket address (protocol/net address/port) is normally permitted
in System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)

in Cassini.Server.Start()
in CassiniService.Service1.WebAppEntry.Start()


and after this is secod similar error, but it references to my web application ("current" is my webapp name):

Exception in Cassini web application [1635, "current"].
Exception:
System.Net.Sockets.SocketException: Tylko jedno użycie każdego adresu gniazda (protokół/adres sieciowy/port) jest normalnie dozwolone

w Cassini.Server.Start()
w CassiniService.Service1.WebAppEntry.Start()

I need to restart Cassini because of updating my webapp. I have to stop Cassini service, swapp some dlls, and start it again. When I got new update, my webapp starts another process which stops Cassini service, updates files and starts Cassini. In this scenario that "another process" has SYSTEM privileges, because Cassini service has them too. When I starts the "another process" manually, eg. in windows command line, all succeeds - in this case "another process" has my privileges (no SYSTEM user, but normal admin user, because my user is in admin group).

Any suggestions? ;)

My methods to start/stop service:

public static void StartService(ServiceController service)
{
if (service == null)
{
throw new ArgumentNullException("service");
}

if (service.Status == ServiceControllerStatus.Stopped || service.Status == ServiceControllerStatus.StopPending)
{
service.Start();
while (service.Status != ServiceControllerStatus.Running)
{
Thread.Sleep(100);
service.Refresh();
}
}
else
{
throw new ServiceAlreadyRunning();
}
}




public static void StopService(ServiceController service)
{
if (service == null)
{
throw new ArgumentNullException("service");
}

if (service.Status == ServiceControllerStatus.Running || service.Status == ServiceControllerStatus.StartPending)
{
service.Stop();
while (service.Status != ServiceControllerStatus.Stopped)
{
Thread.Sleep(100);
service.Refresh();
}
}
else
{
throw new ServiceNotRunning();
}
}


When I swap dlls without stopping Cassini, my webapp sometimes get status "Not running" (in Cassini Explorer)... Because of this I decided to scenario: stop-swap-start.

Hi,

I added some delay (5s) before I started Cassini, but it's still not working. Now in event log I found:

2 warrnings:
Cassini web application [1384, "current"] was stopped but the port was not successfully released.
Cassini web application [7756, "UltiDev Cassini Web Server Explorer"] was stopped but the port was not successfully released.

then 2 infos:
Service was stopped successfully.
Service was started successfully.

and finally 2 errors (like in previous post):
Exception in Cassini web application [7756, "UltiDev Cassini Web Server Explorer"].
Exception:
System.Net.Sockets.SocketException: Tylko jedno użycie każdego adresu gniazda (protokół/adres sieciowy/port) jest normalnie dozwolone
w System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)
w System.Net.Sockets.Socket.Bind(EndPoint localEP)
w Cassini.Server.Start()
w CassiniService.Service1.WebAppEntry.Start()

Exception in Cassini web application [1384, "current"].
Exception:
System.Net.Sockets.SocketException: Tylko jedno użycie każdego adresu gniazda (protokół/adres sieciowy/port) jest normalnie dozwolone

w System.Net.Sockets.Socket.Bind(EndPoint localEP)
w Cassini.Server.Start()
w CassiniService.Service1.WebAppEntry.Start()


Another bug/feature is, that Cassini service won't start when I turn on option "interact with desktop" (in service properties). The message is something like that: "service not respond for start signal".
Why?
