Connection details
The process of satisfying a request for a FlashConnect Web page involves several components.
This diagram describes each component and its role in the process of satisfying requests.
The table below describes the elements of the URL in the above diagram.
| Element | Description |
|---|---|
| http: | Service protocol |
| //www.hostname.com/ | Server name |
| cgi-bin/fccgi.exe? | File to use |
| w3exec=application | Parameter/Value pair |
This example continues using the URL in the diagram above. When a URL is entered into the browser the following occurs:
-
Address portion of the URL (http://www.hostname.com/) is used to contact the Web server at that address and requests the specified page (/cgi-bin/fccgi.exe?).
-
Web server processes the request and, since the requested page is an application, executes the application.
-
Web server starts fccgi.exe, fcisapi.dll, or FCServlet which read and parse the remaining information from the URL (w3exec=application) and any submitted Web form. fccgi.exe, fcisapi.dll, or FCServlet then connect to FCService, passing in the environment variables, including the value of w3exec.
-
FCService sees that a value for w3exec is specified, so it selects an unused connection to the database server and passes the information from the URL and Web form to WWW-IRUN.
-
FCService sends the information to WWW-IRUN and starts the application specified by the value of w3exec.
The process to return information to the browser is:
-
Application uses various FlashConnect API calls to create a Web page. When the application returns to WWW-IRUN or calling w3Input, the Web page created by the application is returned to FCService and FlashConnect notifies FCService whether the connection is persistent or not.
-
FCService passes the information back to fccgi.exe, fcisapi.dll, or FCServlet. If the connection is not persistent, the connection is made available for another user. If the connection is persistent, the connection is reserved and the timeout period is started.
-
fcisapi.dll, fccgi.exe, or FCServlet passes the page back to the Web server and finishes.
-
Web server passes the page back to the browser and finishes.
-
Browser displays the new Web page.
