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();});

$(document).click(function(e) { // ####Check for left button if (e.button == 0) { // alert('clicked'); console.log('page......clicking'); checkhitrate('ads_hitrate');//check the document.activeElememnt source such as ifram or <a> tag }else {}});it works but can not detect mouse right click or mouse left click;so try to other code such as followsvar mouseleft=null;document.addEventListener('mousedown', function(event) { switch (event.button) { case 0: mouseleft=1; checkhitrate('ads_hitrate'); console.log('mouse Left button clicked.'); break; case 1: mouseleft=0; console.log('mouse Middle button clicked.'); break; case 2: mouseleft=0; console.log('mouse Right button clicked.'); break; case 3: mouseleft=0; console.log('mouse Browser Back button clicked.'); break; case 4: console.log('Browser Forward button clicked.'); break; default: console.log('Unknown button clicked.'); }});*/it is working ok, but not work if the content area with iframe...so we need use blur as followswindow.addEventListener('blur', notFocused);function notFocused() { localStorage.setItem('focus','0');setTimeout(()=>{$(window).focus();},200);checkhitrate('ads_hitrate');console.log('NOT focused',ia2++);return 0;}and check whether visitor leave current page to forward to other site, use this function becoz we can not idenity it is right or left click.if .onbeforeunload even is triggered it mean it is from left clickwindow.onbeforeunload=function(e){ console.log('hist-onbeforeunload'); localStorage.removeItem("stateHistoryonbeforeunload"); localStorage.setItem("stateHistoryonbeforeunload", 1);}event onbeforeunload should be earlier than checkrate();function checkhitrate(hitrate){ if (hitrate=='ads_hitrate')sendclick();}function sendclick(){if (document.activeElement.src) var tmp=document.activeElement.src ; else tmp=""if (document.activeElement.tagName === "IFRAME"){if (tmp.indexOf('client=ca-pub-')>0){setTimeout(()=>{console.log('notfocused _post3',"stateHistoryonbeforeunload",localStorage.getItem("stateHistoryonbeforeunload"));document.activeElement.blur(); if (localStorage.getItem("stateHistoryonbeforeunload")=="1"){_post3(url,JSON.stringify(obj),fun);localStorage.removeItem("stateHistoryonbeforeunload")}},200);}}Note: every click then clear last document.activeElement by document.activeElement.blur() so next check click will be working again

no port 80 on window7 with netstat -a -n -o
Asked by duncanb7
at 2024-02-27 01:45:45

Point:500 Replies:7 POST_ID:828889USER_ID:11059
Topic:
Windows 7;Hypertext Transfer Protocol (HTTP);Networking Protocols
Question-1
I restart my Window 7 computer , and type command netstat -a -n -o
to display all network port but I could NOT find any port about 80 (http port)
Why ? and I go to try my other XP computer, it shows the 0.0.0 0:80 on
Local Address from netstat -a -n -o command output.
Question-2
When I open chrome browser on my window 7 computer, and
go to check netstat -a -n -o command, and find the following output
Yes, of course since issue on question-1, I could NOT find any port of 80
But I think about how can I go to google.com default page on my chrome
browser without port 80 listen? And I check the following output, I found
something like
TCP 219.77.4.127:49708 74.125.128.120:443 ESTABLISHED 448
The 219.77.4.127 is my ISP address after check ipconfig command and 74.125.128.120:443 is google.com 's https site.
Why the port for http on my local address is 49708 instead of 80 ?
Or some hidden software installed on my computer to switch port 80 to 49708
such as http proxy ? But I never use any http proxy on my this window 7 computer .
Please advise

Totally agree your comment. Thanks for your reply,
For my memo only:
-the issue in this thread is NOT related to Window 7 & or XP system
-Why my linux server can handle many http accesses with just only TCP/IP http port 80,
that is because apache linux server is multi-process that
mentioned on this link , http://en.wikipedia.org/wiki/Apache_HTTP_Server

Now better understand after your comment and I can verfiy it from that
I go to check the client and server communication port on $_SERVER variable from
php code between my linux server and my window 7 computer
The php code report $_SERVER['REMOTE_PORT'] and $_SERVER['REMOTE_ADDR'] that is
matched to netstat command output on my window 7 computer.
In other words, when I try http://mylinuxsite.com/server.php on chrome browser , it will
go to my server port 80 since http or no http typing will be interpreted as access server TCP/IP port 80 on browser and https for 443.
The connection is between server 80 port and my computer dynamic port when
typing http on browser.
Why it use dynamic TCP port for browser that is I believe because it can use it for multi-thread tasking process so that we can create many instances or type browsers http accesses at the same time wihtout waiting

Google chrome browser uses your local dynamic port to establish a TCP session with google.com.
TCP session is established between your local port and the remote server port. Here the local port will be Dynamic Ports (49152-65535) and the remote server port is 80 for http webpages and 443 for https.
The remote server ports are actually well known port (0 - 1023), it the service that you are accessing will determine which remote port the session needs to be established.

So you mean google chrome browser don't use port 80, Right ?
And why chrome browser USE dynamic ports instead of static port ?

Yes, your computers dynamic port will establish a TCP session with the web-servers well known port (0-1023).
Port 80 is registered for http service and 443 for https. The device that providing these services will open these ports. and the host computers accessing the services will have their dynamic ports open.
Here is the list of ports - Link

In other words, google chrome browser will open TCP session to use dynamic port instead of 80. So the http TCP/IP is not just working on http port 80 only but also other port
such as 49000 to 66500. Right ? Why he is doing that way for dynamic port, for security ?

When we are opening www.google.com your computer opens a TCP session on its local dynamic port with the web servers port 80 ()for http) and 443(for https).
The only time you might see port 80 open on your local computer is when your computer is providing some sort of http services.
