What is X-Forwarded-For in HAProxy?

Since HAProxy works in reverse-proxy mode, the backend servers see its IP address as their client address. This is sometimes annoying when the client's IP address is expected in server logs. To solve this problem, the well-known HTTP header "X-Forwarded-For" may be added by HAProxy to all requests sent to the server.

How to configure SSL in HAProxy?

First, create a self-signed SSL certificate

Use the following command to create your self-signed SSL certificate and move it to /etc/ssl/private. root@haproxy:~# openssl req -nodes -x509 -newkey rsa:2048 -keyout /etc/ssl/private/test. key -out /etc/ssl/private/test.

Where do I enable X-Forwarded-For?

In the main menu of the LoadMaster User Interface (UI), select System Configuration > Miscellaneous Options > L7 Configuration > Additional L7 Header > X-Forwarded-For.

What is the use of X-Forwarded-For?

The X-Forwarded-For request header is automatically added and helps you identify the IP address of a client when you use an HTTP or HTTPS load balancer. Because load balancers intercept traffic between clients and servers, your server access logs contain only the IP address of the load balancer.

What is TCP passthrough?

February 3, 2022. SSL passthrough feature allows you to pass incoming security sockets layer (SSL) requests directly to a server for decryption rather than decrypting the request using a load balancer. SSL passthrough is widely used for web application security and it uses the TCP mode to pass encrypted data to servers ...

What is Http_x_forwarded_host?

I know this is a super-old question, but HTTP_X_FORWARDED_HOST is used when there is a proxy (or multiple proxies) between the browser and your server. If you have this setup: End User -> Proxy A -> Proxy B -> Server. Then, when End User makes a request (with a Host header), Proxy A will receive it.

Does HAProxy use OpenSSL?

HAProxy is compiled with OpenSSL, which allows it to encrypt and decrypt traffic as it passes.

Can you use HAProxy as a forward proxy?

In this presentation, Julien Pivotto explains how Inuits uses HAProxy in an unconventional way: as a forward proxy to route outgoing traffic. This unique use case has uncovered a trove of useful features within HAProxy.

Is HAProxy a good load balancer?

HAProxy (High Availability Proxy) is open source proxy and load balancing server software. It provides high availability at the network (TCP) and application (HTTP/S) layers, improving speed and performance by distributing workload across multiple servers.
