[Client_GetParams] returns a pair array containing an element for each parameter passed along with the URL in the current request.
Check the [Client_GetParams] array. The following example uses the [Array->Find] method to check whether the GET parameters contain an argument for 'Username'. If the parameter is not found then the empty array is returned.
if(Client_GetParams->Find('Username') != array)
'A Username was specified.'
