Example: Specifying a URL Alias
Any Web resource—such as a Web application, a Web portal, or a Web server—can be defined as a URL
resource. Defining a Web resource as a URL provides several advantages:
You can create a Web shortcut for WorkPlace to give users quick access to a URL resource.
You can define very specific access rules to control which users can access the URL.
You have the option of obscuring (or “aliasing”) the internal host name so it is not publicly exposed. When a user accesses an alias, the request is proxied to the downstream Web resource and its private URL is translated using the alias you specify. The user sees only the public (or aliased) URL.
The below image illustrates how the private address for an inventory application might
be translated into a public URL.
Private address translated to a public URL
The private URL for this resource is
http://inventory.example.com, and the administrator has created
an alias for it named
Instead of using the private URL (which would publicly expose a sensitive host name), suppliers access a public
A public URL consists of the following:
https:// prefix rather than
http://: this is because all traffic to and from the SMA appliance is secured using SSL
The appliance’s fully qualified domain name (in this example,
The resource’s alias name (in this example
- Some Web-based applications use Java applets or other browser extensions that submit traffic
using protocols other than HTTP. Examples of such applications include Citrix XenApp and certain
versions of SAP. Although accessed using a Web browser, these applications may need to be
defined as a client/server resource and proxied through OnDemand using the client/server access
- The private URL for which you create an alias must be a directory on the back-end server; it cannot
be a file, and it must begin with either
- Use ASCII characters when specifying an alias. Users who connect to WorkPlace using translated
Web access will see an error message if non-ASCII characters are used.
