To define multiple Web applications or consumers in one configuration file
Select the Append New command from the Web Runtime Configurator File menu. For example, to add two more applications to a file called e:\temp\webappconfig.xml, select the Append New command twice, in which case the example shown in the following image is then displayed.
Expand the node in the pane at the left of each Web application configuration file entity (or Web services consumer configuration file) whose values you want to display in the pane at the right of the window.
To edit the configuration files, click in the appropriate row in the pane at the right of the window and maintain the value in that row to meet your requirements.
Repeat step 3 of this instruction for each value that you want to maintain.
Use the File menu Save As command to save the file to an .xml file name and location of your choice.
