| Subject: | Error when GET parameter without value is sent to a page |

AuthCAS version: 0.1
Perl version: 5.8.7
OS: Ubuntu 6.06, kernel Linux 2.6.15-28-server.
If you send a GET parameter without a value (eg.
visiting /index.php?parameter) to a page that is parsed by AuthCAS, you
get the following error:
Use of uninitialized value in concatenation (.) or string
at /usr/local/share/perl/5.8.7/Apache2/AuthCAS.pm line 872.\n
The error is caused by the following split on row 870:
my($key, $value) = split(/=/, $param)
If there is no = in $param, row 872 complains:
$self->logMsg("PARAM: '$key' => '$value'", $LOG_DEBUG);
Solution:
Check whether $value is set, and if it is not, set it to the empty
string. The following patch does that:
