When using the CGI module
I'm using if(param()) {...} to check wether
there any parameters from a form that is sending them,but
there can also be parameters encoded in the url like http://.../script?param1=val1¶m2=val2
The problem is that this code if(param()) {...},more precise the param() function
is returning true if either the script receives parameters from the URL or from POST parameters
How do I know where the parameters are coming from ?

I can use a CGI object like this to get URL parameters
  5 my $q=new CGI;
  6 my $params=$q->Vars;
  7 $params->{'id'};

and for the parameters which were passed through POST , I can get
those using param('name_of_param');

Thank you
