ON HTTP GOTO is used to defi ne the Fingerprint handler for the 
CGI-request. When a request for an application CGI is received, 
the current execution point will be pushed on to the stack and then 
execution will commence in the handler with stdin and stdout redirected 
from/to the web browser.

Syntax: 

 

<ncon>  

is the number of the line to which the program will  

 

 

branch when the CGI request is received.

<line label> 

is the label of the line to which the program will branch  

 

 

when the CGI request is received.

Remarks: Th

  is statement is used in connection with EasyLAN and 

defi nes a Fingerprint subroutine that handles the CGI-request. Setting 
the handler’s line number or line label to 0 disables it. When a request 
for an application CGI is received, the current execution point will be 
pushed on to the stack and then the execution will commence in the 
handler with stdin and stdout redirected from/to the Web browser. 

When RESUME HTTP is executed, the application layer fi nishes 
and the web server closes the TCP-connection and pops the execution 
point so that the program continues where it was before the request was 
received. Stdin and stdout will be restored to their original values.

If mode is set to interrupt but the program is not running, the error 
message “Application not started” is shown when the resource is requested. 
If ON HTTP GOTO is defi ned, the interrupt handler will be called 
even for other Fingerprint CGI-programs, and it is up to the application 
to handle/honor this.

To look-up which program that was requested, you should use
