this particular instance of call is from a radius server (perl or C),
so it is not interacting with the web server at all, no browsers... a
shell script for all intents and purposes, which parses the db for the
required aiuthentication info and processes the request accordingly
(along with other tasks).
perl scripts for example, can exit back to the calling program with a
return code or value. for example, the following when called by
another program will return a 0
#!/usr/bin/perl
$ret=0;
exit $ret;
if conditions are not met, you can pass a "failure" notice to the
calling program depending on the value returned.
would like to do the same with the php script, but it returns the
variable prior to exiting (ie printing it to the screen) rather than
passing it back
