I am using cloudflare to protect my website recently,but I have a page which is using python socket to send streaming data to visitor with 5000 portsuch as http://mywbesite.com:5000.Before using clouldflare, visitor can get data from port 5000, now after usingcloudflare, all visitors to my website can not get any data from port 5000.Now I pause cloudflare, the python socket port is working back again..The question is I would to like to keep all cloudflare service such as proxy but python socket port need to work for exception by cloudflare, how can I do that ?My Simple python socket code:from flask import Flask, render_template, request, session,jsonifyfrom flask_sse import ssefrom flask_socketio import SocketIO, emit, join_roomimport platformimport loggingfrom flask_cors import CORSimport socket....if __name__ == "__main__": app.run(host="0.0.0.0",debug=False, port=5000, ssl_context=("mycert")

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();});

Do I need to use Mysql ?

Topic:
MySQL Server;Oracle Database;PHP Scripting Language
I studied SQL before , and the code is easy I think or that I might not experience tough code.
The question is as follows.
1- If I am really familar with php or c coding, do I still need to use mysql if my number of
users are just 100,1000,10000, for example only ? Why I ask this question becoz
sometimes, there is a lot language or website Sql monitor service, login and password to be kept in our memory. If for non-programmer, I think mysql is easy for them, If you are good programmer, I think Mysql is no need for you, Right ?
2- If question one is yes, not neccessary to use mysql if you are good programmer with
just handling 10000 users,
Why Oracle is so big on database technology, what is behind ? Is it becoz they can handle
100000000000000000000000000 or infinte data entry database for users with using its
system ? Or they are doing well on security on database not just huge database entry
3- I want to give up to use Mysql since I'm familar with php and users is just 10000 only. Do you think that is saving time for me and save money to pay Mysql monitor service ?
Since I strongly believe php code can cover Mysql coding
Please advise

So, we are back at free and your comment "testing purpose only for cutting cost" is not accurate. Free versus your development time to write database code.

I am willing to pay but too many package to need to pay that is not important

Most of the time, in this world you get what you pay for. If you don't want to pay the price for a product like Oracle and you want to use a "free" database tool instead, you can do that. You just won't get the features that Oracle includes.
Or, if you prefer to take the time to build your own record-keeping system using php or c and simple *.csv files, you can do that. But, you may find this takes you a long time, and you may encounter problems that databases already have built-in features to handle (thing like: multiple users, record locking, data concurrency, security, etc.).
Just like if you want to travel from Paris to Singapore, you don't have to buy a plane ticket - you could walk. It is the same with computer databases. You can buy one that includes lots of features and allows you to quickly set up an application, or you may choose to build you own. No one is forcing you to buy an Oracle system.

So next thing, why Oracle is so big to dominate all Sql database market becoz
they handle Infinite data entry or database using Sql or doing well on databse security
that other languages can not handle it, even it is possible for other language but need a
time to develpe but the market is already on his hand.

It sounds like you have already made up your mind to not use databases and are looking for us to confirm this. Sorry, I cannot.
It boils down to return on investment.
Can you 'buy' something cheaper than you can write and maintain it?
It's also hard to build in relationships to a flat file CSV layout.
As far as the monitoring service: Do you have to use it?

next cases, when go to free tool of mysql but mysql monitor service is another service and that
also need to pay...Just think you go to move every step on internet, need to pay

Use the data base. You obtain no advantage by avoiding it. Choose any PHP extension except MySQL.
Oracle is successful because they have a great many salesmen who are highly paid to tell everyone that Oracle is a good product.
None of this has anything to do with being a "good" programmer. It's about choosing the tools that give you the most advantage. But the question sounds kind of like, "If I am a good carpenter, I do not need to use power tools?"
