Notes
App quit defaults:
- CGI apps quit when there are no more connected sessions (AutoQuit can be used to change this default).
- Standalone apps do not quit unless the Quit method is called (AutoQuit can be used to change this default).
Session is not available from WebApplication event handlers.
CGI Web Applications only listen on the localhost interface.
ApplicationIdentifier must be specified in order for your web application to work. |
Command-Line Parameters
When starting a stand-alone web application, you can supply these parameters on the command line:
Command | Description |
---|---|
--port | The port the web app listens to for a connection. This can be used to change the port that was used to build the web app.
--port=9191 |
--MaxSockets | The maximum number of allowed connected sockets. The default is 200. This is not the number of maximum users as the number of connections does not map one-to-one with the number of connected users. Do not set the value too high as it will increase memory and CPU usage.
--MaxSockets=300 If you do not want any unsecured connections, set this value to 0. |
--MinSockets | The minimum number of allowed connected sockets. The default is 20.
--MinSockets=50 |
--SecurePort | The port the web app listens to for a secure connection. This can be used to change the port that was used to build the web app.
--SecurePort=9898 |
--SslType | (Available in 2016r1) Allows you to specify the type of security used. You can use these integer values: 3 (TLSv1), 4 (TLSv11), 5 (TLSv12, the default)
--SslType=4 |
--MaxSecureSockets | The maximum number of allowed secure connected sockets. This is not the number of maximum users as the number of connections does not map one-to-one with the number of connected users. Do not set the value too high as it will increase memory and CPU usage.
--MaxSecureSockets=300 |
--NetworkInterfaceIndex | The index value (of NetworkInterfaces) to use as the NIC for connections. 2017r2 or later also accept the value "Loopback" to allow listening only on the loopback interface.
--NetworkInterfaceIndex=1 --NetworkInterfaceIndex=Loopback |
--SecureNetworkInterfaceIndex | (Available with 2017r2) The index value (of NetworkInterfaces) to use as the NIC for secure connections. 2017r2 or later also accept the value "Loopback" to allow listening only on the loopback interface.
--SecureNetworkInterfaceIndex=1 --SecureNetworkInterfaceIndex=Loopback |
--Certificate | The path to the SSL certificate (available in 2015r2).
--certificate=/full/path/to/file |
--Logging | The path to HTTP Log file.
--logging=/full/path/to/file |
Using SSL with Standalone Web Apps
Refer to the UserGuide:SSL for Standalone Web Apps topic for more details on how to set up a standalone web app with SSL.
