We are going to develop a web application in local network for a company. We can't use IIS because of some limitations, e.g. print document on server side programmatically and GUI processes. But with IIS Express because of running mode, we are able to access all resources that we need, But I'm not sure about performance. I have no idea what will be happened when the Application being used by 70 users. how can i handle this?

  • I am not entirely sure this question belongs on Stack Overflow. However, there is no problem with printing on printers on the server with IIS, and why do you want a web server to show dialogs on the web server? IIS Express is not intended for your scenario; IIS is. Official statement: [Internet Information Services (IIS) 7.5 Express is not supported in a production environment](https://support.microsoft.com/kb/2562885). – Andrew Morton Oct 25 '14 at 19:03
  • @AndrewMorton I've had problems with printing on the servers, even I create an external application only for printing purpose, and I execute the application in the web application but it didn't work. If you have a good solution please share it, I did a lot of stuff for this, e.g. changing the application pool, working with IIS_USERS group and etc. but it didn't work. – Saman Gholami Oct 25 '14 at 21:25
  • @Saman, a web application on IIS in system session won't print, and you should rearchitect the whole system, to be a web application + message queue + a client for printing. The client running in a user's session can subscribe the message queue and print tasks out. Using IIS Express is obvious just a dirty workaround and you should never consider it for production. – Lex Li Oct 26 '14 at 12:17
  • @LexLi I can't use your solution because i need to print document real-time, but I think your solution needs an iterative process on client machine for checking the message queue. – Saman Gholami Oct 26 '14 at 20:06
  • @SamanGholami it is rather strange that you thought message queue is not `real-time`, http://en.wikipedia.org/wiki/Message_queue – Lex Li Oct 27 '14 at 12:55
