Custom web application (Site’s host name)

In general, there are organizations that use their own applications to bring about their purposes and accomplish their tasks in a unique way. Some may use uncommon applications that cover their purposes and not all are highlighted as application templates. But TAC is capable of publishing those uncommon or organization’s unique applications using Custom Application templates.

TAC provides two types of custom web application templates: 

  1. Custom web application (Site’s host name) 

  1. Custom web application (own host name)

Administrator may publish almost all types of generic web applications using either custom web application (Site’s host name) or custom web application (own host name) template. 

Please identify which application template is best suited to publish your own application through TAC.  

Definition of a Custom web application (Site’s host name):

The term “Site’s host name” in the custom web application is used for applications that are accessed using Site’s host name. What if the Site has many applications that are using Site’s host name?  How does TAC identify which request comes to what server? The answer is: Site’s host name application, known as non-AAM (Alternate Access Mapping) like applications, are using its site host name with a unique ID to launch the applications. Applications published using the Site’s hostname template use the Site’s host name and therefore rely upon the HAT mechanism (or Host Address Translation).  

Example:  The TAC Site’s host name is the same for all published applications.  Therefore, when a request comes to TAC using Site’s host name, how does TAC identify which relevant application to publish the request?  This is where HAT becomes relevant.  When the Host Address Translation comes into play to identify the request, TAC attaches a unique ID to each incoming request and the request is then sent out to the appropriate internal server.
