02:53.650 --> 03:00.730 It is not secured and we will shift this a little bit again so that I can be able to explain more on 03:00.730 --> 03:01.150 this. 03:01.150 --> 03:07.480 So let's go ahead and drag this right in here because we need to work on this URL parameters and we 03:07.480 --> 03:09.670 will understand what we are doing. 03:12.010 --> 03:12.400 All right. 03:12.400 --> 03:18.370 Now you can see that this is not very secured because it's in a password. 03:18.370 --> 03:19.990 You're going to see the password right in here. 03:19.990 --> 03:26.860 And I can actually go and say because we have site dot PHP and this question mark goes username equal 03:26.860 --> 03:27.400 to these. 03:27.400 --> 03:35.620 So what if someone go ahead and put in ampersand and uh let me say so I have this which we did previously 03:35.650 --> 03:37.930 say ampersand age equals 24. 03:37.930 --> 03:39.160 If I go ahead I click on this. 03:39.190 --> 03:40.750 Nothing actually happens. 03:40.750 --> 03:44.320 But if I go right in here I change the username to age. 03:44.350 --> 03:46.510 Save this refresh. 03:46.540 --> 03:49.000 You can see I have 24 printed out here. 03:49.210 --> 03:53.320 Even though we don't have this, it's being saved on the URL. 03:54.250 --> 03:55.090 You can see that. 03:55.090 --> 03:57.850 So it means we need to secure. 03:57.880 --> 04:01.000 This is very very important though. 04:01.000 --> 04:03.970 This is a very good rule in Google. 04:04.000 --> 04:05.530 Let's say we go over to Google. 04:05.560 --> 04:07.090 Let's open up Google. 04:07.090 --> 04:12.190 And uh Google is one of the platforms that you use expose URL. 04:12.220 --> 04:13.720 I don't actually know why they do that. 04:13.720 --> 04:19.900 So we can see just like we have here, if we go back to Google and search this like let me say Cat, 04:20.720 --> 04:22.250 Um, I just cut. 04:22.280 --> 04:23.690 Now look over here. 04:23.720 --> 04:25.970 Google has the URL exposed. 04:26.000 --> 04:28.100 I don't actually know why they did that. 04:28.130 --> 04:28.940 You understand? 04:28.940 --> 04:34.790 So you see slash Q equal to cut and ampersand equal to all this. 04:34.790 --> 04:36.290 So I don't know why they did it. 04:36.290 --> 04:42.080 Now if I go ahead and, uh, copy whatever that is here I'll get to the end. 04:42.110 --> 04:44.060 I'm copying everything to the end. 04:44.090 --> 04:48.290 And when I get to the end, I'll delete this from the Google URL. 04:48.320 --> 04:52.670 I can go to slash for, like, cattle and type cattle. 04:52.700 --> 04:55.220 Remember, I'm not doing this from the page. 04:55.220 --> 04:56.420 I'm doing it from the URL. 04:56.420 --> 05:00.260 And if I hit on cattle, it'll go ahead and search about cattle. 05:00.950 --> 05:01.670 You see that?
