What is our observer and how it works?

2
00:00:04,990 --> 00:00:13,650
Observer is a place which stores processes and delivers Web pages to a client's.

3
00:00:14,770 --> 00:00:21,430
What clients is nothing but our browser on our laptops and smartphones?

4
00:00:23,360 --> 00:00:24,830
As you can see in this image.

5
00:00:27,660 --> 00:00:37,860
The communication between client and server takes place using a special protocol called Hypertext Transfer

6
00:00:37,860 --> 00:00:40,950
Protocol, which basically HDTV.

7
00:00:41,310 --> 00:00:48,990
I think that you are familiar with this one because you see it in almost all length and all pages in

8
00:00:48,990 --> 00:00:51,960
this protocol, the client here.

9
00:00:53,560 --> 00:01:03,370
Initiates communication by making a request for a specific Web page using ECB protocol, and the server

10
00:01:03,370 --> 00:01:12,580
then responds with the content of that Web page or an error message if it was unable to do that, like

11
00:01:12,580 --> 00:01:22,540
the famous 404 error page, pages delivered by a server are mostly assembled documents or PSP documents.

12
00:01:23,630 --> 00:01:25,990
Now, let's take a quick example.

13
00:01:28,820 --> 00:01:35,400
This browser is our client now free, right?

14
00:01:35,420 --> 00:01:36,500
Google dot com.

15
00:01:39,020 --> 00:01:49,040
It will provide HDTV, which we already mentioned, and it will ask the server to deliver this Web page,

16
00:01:49,040 --> 00:01:50,210
which is Google dot com.

17
00:01:50,940 --> 00:01:59,540
Now, this request will go from the old client, which is this browser to Google servers and Google

18
00:01:59,540 --> 00:02:04,930
servers will respond with this page content, which is basically an image and two buttons.

19
00:02:05,630 --> 00:02:13,670
So this is us communicating with Google server using our old client, which is this browser.

20
00:02:14,390 --> 00:02:22,610
I think now that this idea is more clear and we are going to transfer our PSP board to our Web server

21
00:02:22,940 --> 00:02:31,940
and we are going to write an e-mail code so that whenever someone sent a request to our export server,

22
00:02:32,300 --> 00:02:37,250
it will respond with the pages that we did create inside it.

23
00:02:38,640 --> 00:02:39,870
Thanks for watching this lesson.
