How to block user agent cloudflare?

Hello I am building a web page and my idea is to make it secure by blocking all the agents with cloudflare.

Can you help me to find some example or give some idea on how to do it.

I'm not using cloudflare for its anti-spam, but I just wanted to have my website is secure because of malware issues. That's why I use cloudflare and I don't want to be vulnerable to spam Yes! Cloudflare makes your website more secure and faster. But you should not allow user agents to connect to your website using Cloudflare's DNS service because they may send your users' passwords to their servers.

Cloudflare DNS service is intended for Cloudflare customers only and is disabled for anyone else. You can still use Cloudflare for hosting, Cloudflare makes your website faster, but please do not use Cloudflare DNS service for anything else. Thank you.

For your information, you will not be able to access the site if you leave the following fields blank: I think it's more important to be able to easily identify the reason of a failure, and to be able to debug the problem. This is useful to a site owner who wants to know the reason of a user's visit. If the reason is clear then we can determine whether to block him, or let him continue his visit.

For this reason I prefer to have a specific URL that redirects users to the admin pages of the site. The problem with the 'block', if I understood correctly, is that a visitor can easily bypass it because he sees the source code of the page. But the purpose of the 'block' is to block the user agents from a specific IP address.

In addition I think that the admin page of the site can be redirected to the administration page of the Cloudflare DNS service. For example: /dnsadmin. If this solution is implemented we will be able to find the reason of a failure, because we know exactly where the issue is. The user agent who has accessed the site will be redirected to the DNS server, and then we can block him.

If this will be implemented, I think that the users of the site will not be frustrated by the fact that the admin page is difficult to access.

How do I block CloudFlare?

How to block CloudFlare for your traffic, and why you should be concerned with it.

CloudFlare is a free service that offers a lot of benefits to people running websites. However, in the event of a DDOS attack, CloudFlare is known to mitigate the attack for the end user by hiding the attack source.

If you ever want to block CloudFlare for your traffic, you need to get your IP address hidden from CloudFlare. This can be done through the use of a VPN, but there are other ways as well. Let's find out what each of those options are and why it's a good idea to block CloudFlare for your visitors.

Why you shouldn't block CloudFlare. When CloudFlare blocks your IP address, they do so by having your IP address hidden from their global network, which includes all CloudFlare endpoints. The only IP address CloudFlare sees is the IP address of the CloudFlare Edge proxy that CloudFlare has set up on your behalf.

When someone tries to access your website or site from your domain name, CloudFlare will attempt to see if it can reach that IP address. Since your IP address isn't known to CloudFlare, CloudFlare doesn't route any traffic to you, and your visitors will never even know you had an issue.

If you visit CloudFlare's website, it will state The following website isn't optimized for CloudFlare:. When you visit your own website's website, it will often state This website isn't optimized for CloudFlare. It doesn't state Your site isn't optimized for CloudFlare since it can't see your IP address since it's not connected to the CloudFlare network. When you view the blocked IP addresses, it'll look something like this: If you have a legitimate IP address in the list of IP addresses, you will be able to visit your site normally without any issues, but if it's an IP address that was used to cause a DDOS attack, CloudFlare would have to hide it, since the DDOS attack would be against CloudFlare, not you.

What is user agent in proxy logs?

I'm trying to figure out what does it means user agent in proxy logs.

Does it mean user agent that is used by my server and client when I connect to a proxy? I have two servers. One of them has the proxy configured on it. Another one doesn't have.

The second server should be able to pass all requests (including SSL) to the first server. How do I know which is the correct user agent? If I try to use both servers, they behave the same.

There's no way for you to tell, because there's nothing to compare them to. You'll get the same results from either. There's nothing to be sure about. You can only know which one of the two is acting as a proxy. It will be revealed in the logs when the proxying server sees your request for the first time.

Thank you for your answer. But in this case how do you know that the server that I'm connected to is a proxy or not? I've tried two servers - one with proxy configured and another one that doesn't have a proxy. Both of them acted the same.

In the logs you will see the name of the server that sent the request. As you've noticed you need to be connected to at least one of them, otherwise the server names won't be enough to identify the proxy.

Yes, in this case user agent means the browser that sent the request, not the client program. The server that acts as a proxy is supposed to identify itself as what it is. You won't see that unless it sends information to indicate it. For example, you could have a proxy set up on your local machine and connect to the server with a certain user agent.

And how do you know it? For example how can I be sure if the first server has a proxy configured or not? You can't be sure. Your proxies should say This is me.
