WEB Server list


WEB Server list -> Function result

Parameter	Type	Description
Function result	Collection	Collection of the available Web Server objects

Description

The WEB Server list command returns a collection of all Web server objects available in the 4D application.

A 4D application can contain anywhere from one to several Web servers:

1 Web server for the host database (default Web server)
1 Web server for each component.

All available Web servers are returned by the WEB Server list command, whether they are actually running or not.

Note: The default Web server object is automatically loaded by 4D at startup. On the other hand, each component Web server that you want to use must be instantiated using the WEB Server command.

You can use the name property of the Web server object to identify the database or component to which each Web server object in the list is attached. For a detailed description of the Web server object, please refer to the WEB Server command.

Example

We want to know how many running web servers are available:

 C_COLLECTION($wSList)

 C_LONGINT($vRun)

 

 $wSList:=WEB Server list

 $vRun:=$wSList.countValues(True;"isRunning")

 ALERT(String($vRun)+" web server(s) running on "+String($wSList.length)+" available.")
