After clicking some Googe Ads and leave the ads site or delete the tab, your browser may forwards you to other site which may give you message such as "Congrulation,! You Get Prize, Bonus, Coupon.etc" Probably your browser is infected by virus and the Congurlation site is hacker /attacker virus site.. I will think the following methods to solve my problem, Please advise those methods are correct 1- Right away or now, remove the forwars site(Congrulation site) or delete such browser Tab 2- Look at this image: https://computer28.com/image/deletecache.jpg Delete or clean your chrome browser data At Chrome browser, Click Sitting->Privacy Security->Delete Browser Data, it will pop up window, in that window, Click Advanced->Select Time Range(All Time)->Tick all box below Time range such as Browsering History..etc. Click Delete Data button 3-If using Window 10, Turn on Microsoft Defender Virus Protection System, always turn it on https://carleton.ca/its/help-centre/how-to-enable-windows-defender-on-personal-pc/ You are better to install Microsoft Window 11 if u are using WIndow 10 4- Add X-Content-Type-Options: nosniff on header at my apache server

Visitors or users may open many page of website to get streaming data ,and they want to open many browser tabs to read different data. That will depend on your Laptop or mobile capiblity how can handle many new socket.io to run on multiple tab at the same time, If limited computer resouce or memory, you will be limited for number of browser tabs display.If u use socket with Redis /stream event that allow display directly into html page tab (just type https://yourdomain:5051/stream on address bar) or throught javascript parse data into html page but it may only allow 3 tabs running on the same time.How you can run it on many tabs ?-----------------------------------------------1-You can use localStorage(getItem or setItem) to share information between browser tabOr...you can use2-window.addEventListener('blur', notstream);window.addEventListener('focus', stream);When the user not read or not focus the tag, close the streaming socketio, then Whenthat users want to read it again and focus the tag, reconnect the socket. We know users only can read 1 tag at a time only,function notstrem(){souce.close();//close the socket.io}function stream(){//user focus the tab againrefresh();// re-run that funation u can stream data before}function refresh(){//Redisvar source = new EventSource("https://yourdomainsocket-site.com"+":5051/stream"); source.addEventListener('publish', function(event) {dataextract(event.data);if (typeof ws=='function')ws(event.data);if (typeof updatechart=='function')updatechart(event.data); }, false); source.addEventListener('error', function(event) { }, false);return source;}let source=null;jQuery(document).ready(function($) {console.log("onload");source=refresh();});

Topic:
Apache Web Server;;PHP Scripting Language
As I know DNS server is for registering domain name.
For example, my webiste , www.mysite.com which is registerd
on DNS server by DNS server owner so that people
can access my domain address in IE broswer to access my webage.
Most Web Hosting company are DNS server owner, Is that right ?
They are registered from International Internet committe to be
DNS server and provide service for user domain name registration , Is that right ?
So normally users' linux server computer can NOT be DNS server because
users don't have right to register domain name into internet.
Or all DNS server is at telecom ISP service provider company who already
grant a right from its local goverment to be DNS server to connect
the global internet netweork, Is that right ?
And hosting company just buy and pay the service from ISP company to
provide domain name registration service for users ?
Just want to know what is the major role for every party in www internet world ?
Please advise

I think the experts gave enough information.
Usually the DNS is a computer server that has a software installed on it, this software include a list of domain names and the IP Address for that domain.
This software usually listen on port 53 for incoming connections, when you give the browser a host name, for example: www.mysite.com, the browser don't know where is the server located, so the browser need to get this host IP Address, this is called resolving DNS, it connect to the DNS server and give it the domain name, the DNS server find the domain name in the list and give the server IP Address.

In the UK the registration scheme for the .uk TLD, is controlled by nominet.org.uk, it's independent from government and has been around for 20 years, see http://www.nominet.org.uk/about/background/history/
Nominet will allow almost anyone to become a UK registrar or simply register domains, on an ad-hoc basis, see: http://www.nominet.org.uk/governance/members/ and for a list: http://www.nominet.org.uk/registrars/becomeregistrar/taglist/
A number of colleagues in the past have been registrars in their own right, and all the medium / large companies I've worked for have been registrars, as they've needed to register up-to several thousand variants of the companies trading name(s) / brands, to prevent cyber-squatting.
Having a DNS server is another matter, almost every ADSL modem and router has the capability, let alone the servers you'll find in the average company. So most medium / large companies host their own DNS entries (slightly harder to hijack, and quicker). All that's required is that you nominate two devices (DNS servers) as responsible for owning a particular domain name, in it's DNS record.
Many smaller companies, and geeks, and part-time registras have their own DNS servers.

"so I beleive in every where in the world, even in China, all DNS server

No. But that may be true country TLDs. I know that's the case for Canada, Tuvalu and some others, but I don't think that's the case for the US or the UK.
"I think no one can own DNS server conneted to internet with ICANN requirement
besides you are ISP company with govenment access grant."
I own a DNS server connected to the Internet. It's how people find services offered by my network.
"So in other words, only big company can own DNS server to connect to internet..."
No, at least not in the US. I can't speak for anywhere else.

"I connect to internet through my ISP such as AT & T in US,
and I type www.mysite.com on my IE broswer.
www.mysite.com will go to DNS server to check its domain name validaity
Who will check it, AT & T 's DNS server, Who will check it ?"
Your browser goes to an invisible DNS server called "root" (represented by a period - .) to ask how to find a DNS server responsible for the .com TLD. The browser then goes to the .com DNS server and asks how to find a DNS server responsible for mysite.com. Your browser then asks the mysite.com DNS server how to find the machine called www.mysite.com. The browser then attempts to connect to that machine using port 80 (or 442, or whatever) and so it goes.
This process is true for all DNS resolution, however the process is sped up by having DNS servers cache requests they've made recently so they can answer new requests faster.

Your own ISP probably owns the site that handles unresolved DNS pointers. At least that's fairly standard in the USA.

Okay, it is more understanding...
Now for example,
I connect to internet through my ISP such as AT & T in US,
and I type www.mysite.com on my IE broswer.
www.mysite.com will go to DNS server to check its domain name validaity
Who will check it, AT & T 's DNS server, Who will check it ?
When I type wrong domain name address, my brower will show error
message from this website. Who own this website, Why they are
doing for users for domain name checking, for what ?

My links describe - for some scenarios - what's involved in becoming a Domain Registrar. Just about anyone can do it, but there are requirements that have to be met.
ICANN is an international organization established to monitor/manage domain names, among other things.
DNS servers are located all over the world. What and where depend on what you're looking for. I host my own DNS for my domain, but I don't have to, and many people don't.

A domain name registrar can grant you a license to use a domain name. You pay then for this, usually a few dollars a year.
A domain name server is a computer on the internet that translates your domain name into the numeric URL that allows message routing around the internet.
Most hosting companies are either domain name registrars or have a relationship with one of the large registrar companies. Domain name registrars are often hosting companies, too. Some examples of DNS registrars include GoDaddy, Enom, TuCows, etc.
