Text Conventions

The following text conventions are used in the Kaazing Gateway topics:

Convention Meaning
${variable} A variable within the dollar-sign and curly brace format specifies a property default value in the Gateway configuration file, for example GATEWAY_HOME/conf/gateway-config.xml. Property default values are propagated throughout the configuration when the Gateway starts. For example, you could specify as the default value for the ${gateway.hostname} property. Variables shown in italics but without the dollar-sign and curly brace format indicate placeholder variables for which you supply particular values.
bold Bold typeface indicates graphical user interface elements associated with an action, or terms defined in text or the glossary. It also indicates your location in a series of steps such as in the “Before You Begin” section in any procedural topic.
italic Italic type indicates book titles, emphasis, or placeholder variables for which you supply particular values.
monospace Monospace type indicates commands within a paragraph, URLs, code in examples, text that appears on the screen, or text that you enter.
An ellipsis indicates that a portion of an example that would normally be present is not shown.

About URI Syntax

The Gateway documentation uses a generic URI scheme that has the following components:


For example, the following URI schemes are used in the documentation:





In addition, you can append a query string to the URL to provide non-hierarchical information. The query string follows a question mark (?) appended to the URL. For example, you can use this query string when configuring security for your Gateway (as described in the Security Reference).

Note: In the example URLs, the ${gateway.hostname} syntax allows you to define property values once and then the values are propagated throughout the configuration when the Gateway starts. You can replace any value in the configuration file that uses the dollar-sign and curly brace format (such as ${gateway.hostname}) with a property. In the Gateway configuration, you can configure property defaults such as gateway.hostname, gateway.base.port, gateway.extras.port.

About Domain Names

Many examples in the documentation use the .net domain (such as tcp:// to indicate internal, nonpublic URLs, and use the .com domain to indicate public URLs. All domains and URLs are for example purposes only. Simply replace any instances of “” in the configuration with your domain or hostname.

About Kaazing_HOME

By default, when you install or upgrade Kaazing Gateway, the Kaazing_HOME directory is created. This top-level directory contains the Kaazing Gateway directory (referred to as GATEWAY_HOME) and Gateway components. The value of GATEWAY_HOME depends on the operating system. See About GATEWAY_HOME to learn more about Gateway directory destinations.

This documentation assumes you are running the Gateway from the default location. You may override the default and install Kaazing Gateway into a directory of your choice.


This is the directory that contains Kaazing Gateway and its components. The default Gateway home is represented in the documentation as GATEWAY_HOME because the actual directory destination depends on your operating system and the method you use to install the Gateway. If you download from and unpack the Kaazing WebSocket Gateway, then you can unpack the download into a directory of your choice (for example, C:\kaazing or /home/username/kaazing).
