CGI Error Meta-tag

DL_CGIError – Overrides DDU error page redirection and replaces it with a reference

to a CGI script which is passed the error number as an argument.

Content – A CGI URL with variable name argument in place. The name of both the

CGI function and the error number variable is completely configurable by the user.

Do not put an ‘=’ at end of the URL.

HTTP header error numbers are returned if they are greater than or equal to 300. For

example, ‘404’ is returned if object is not found on the server. In addition the following

WebAppLock specific error numbers are returned:

Error Number Error Condition

1000 WiFi is disconnected

2000 Failed to open internet connection with WiFi

3000 Failed to connect to server

4000 Failed to open page on server

5000 Failed to send query to page on server

6000 Failed to receive query from page on server

7000 Failed to find file on device

Warning: Error redirection from the WebAppLock tab in DDU will be ignored if a page

has this meta-tag defined.

Example:

bin/errorpage.plx?errornum">

In the event of a 404 error (object not found on the server), WebAppLock will

navigate to the following URL:

http://www.SOMEWHERE.org/cgi-bin/errorpage.plx?errornum=404
