Re: Reuse backend connections

Not for Remote desktop protocol, it is for haproxy backend server with option persist as in "HAPROXY_0_BACKEND_HEAD": "\nbackend {backend}\n balance {balance}\n mode http\n option httplog\n option forwardfor\n option http-keep-alive\n option persist\n http-reuse aggressive\n maxconn 16\n",

Bryan, One another follow-up question - what does persist do? Thanks! -Leela From: Bryan Talbot Date: Friday, June 29, 2018 at 12:40 PM To: "Leela Kalidindi (lkalidin)" Cc: HAproxy Mailing Lists Subject: Re: Reuse backend connections On Jun 29, 2018, at Jun 29, 12:38 PM, Leela

Re: Reuse backend connections

Hi Bryan, Thanks a lot for the prompt response. Is there a such kind of thing to leave the backend connections open forever that can serve any client request? -Leela From: Bryan Talbot Date: Friday, June 29, 2018 at 12:30 PM To: "Leela Kalidindi (lkalidin)" Cc: HAproxy Mailing Lists

[PATCH] MEDIUM: proxy_protocol: Send IPv4 addresses when possible

This patch changes the sending side of proxy protocol to convert IP addresses to IPv4 when possible (and converts them IPv6 otherwise). Previously the code failed to properly provide information under certain circumstances: 1. haproxy is being accessed using IPv4, http-request set-src sets a

Reuse backend connections

Hi, How can I enforce haproxy to reuse limited backend connections regardless of number of client connections? Basically I do not want to recreate backend connection for every front end client. "HAPROXY_0_BACKEND_HEAD": "\nbackend {backend}\n balance {balance}\n mode http\n option

Re: Connections stuck in CLOSE_WAIT state with h2

Hi Willy, I'm back at work after 2 weeks on the beach in Dalmatia. I've patched my Haproxy 1.8.11 with all three patches discussed here in last two weeks. It didn't help. Then tried to run Haproxy with debug enabled. The last logs from FD hanging in CLOSE_WAIT looks like this:

Re: Reverse String (or get 2nd level domain sample)?

Hi, converters are just simple C functions, (or could be Lua code as well), and are quite trivial to write. Instead of creating a converter that reverse the order of chars in a string, I would rather patch current "word" converter to support negative integers. IE: -2 would means you extract the

Re: Haproxy health check interval value is not being respected

Hi Adwait, So, you have a "timeout check" set to 5s as well. Are your servers UP and RUNNING ? If not, then timeout check would trigger before interval, and HAProxy would retry a health check (up to 'fall' parameter). (timeout connect might also trigger a retry if a S/A is not received by
