Can HAProxy use the port that is part of the domain?

I am setting up a cluster of servers which all run a dynamic number of services on some random ports. Each service binds to the same port on all servers.



I would like to put HAProxy in front of these servers to load balance the incoming traffic, and give clients a predictable entrypoint into the service, given they know the port of the service.



Here's a rough example of how I would like to map a given domain to my three servers. The wildcard *.example.com is pointing to the HAProxy.



32001.example.com:
 - 10.0.0.1:32001
 - 10.0.0.2:32001
 - 10.0.0.3:32001

32002.example.com:
 - 10.0.0.1:32002
 - 10.0.0.2:32002
 - 10.0.0.3:32002

...

35999.example.com:
 - 10.0.0.1:35999
 - 10.0.0.2:35999
 - 10.0.0.3:35999

36000.example.com:
 - 10.0.0.1:36000
 - 10.0.0.2:36000
 - 10.0.0.3:36000

...


Is this possible without creating a humongous config file?

  • I don;t think so, because haproxy needs to be able to check the health of the backend servers independent of what requests come in. So it needs to know the IP/port of all backend servers beforehand. Perhaps haproxy is not the right tool here.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this
