RE: help with long connect times and timeout
Hi Ricardo, I'm using the current defaults and added this to the config: Can you post the full configuration? The part about timeouts is important in this case. Also, please specify what release you are using. However once I startup haproxy, and I attempt to connect to the proxy from the outside server, it usually (95% of the time) takes a few seconds for the connect to establish and sometimes it even times out and the connection is closed. However, even though going from the outside server through haproxy I get delays and timeouts, I can still go directly from the outside server to any of the 3 servers above without any delays or timeouts. The issue is only when going through the proxy That sounds like simple packet loss issue to me. Can you tcpdump frontend and backend traffic of such a broken session? Could you start haproxy in debug mode, reproduce the issue and post the log? Regards, Lukas
Question concerning the server entity
Hi all, for my understanding. When I have a declaration in HAProxy 1.5.x like the following: frontend F1 default BE1 frontend F2 default BE2 backend BE1 server S1 IP1:Port1 server S2 IP2:Port2 backend BE2 server S1 IP1:Port1 server S2 IP2:Port2 Is then S1 (identified by IP1:Port1) ONE entity or are BE1-S1 and BE2-S1 two entities and HAProxy does not set this both into relation? E.g. for doing a check not for every backend/server combination but for a server alone. Best regards Andreas Mock

I don't think it's worth releasing a new version before we merge Simon's work, considering that there is almost nothing new. Willy

If you want to avoid sending health checks twice, you can have one do the checks and the other track the first one (please check for track and check in the config manual). Regards, Willy
AW: Question concerning the server entity
Hi Willy, thank you for your answer and your hint concerning check and track.

Delete response headers unless condition give me a warning
Hello, I'm trying to delete some headers in a frontend based on a condition, but when i set the acl: acl header_app hdr_cnt(X-JSON) gt 0 rspidel ^X-.* unless header_app A warning message is print: acl 'header_app' will never match because it only involves keywords that are incompatible with 'frontend http-response header rule' Configuration file is valid I don't understand exactly how can i do that. Any alternative? Thanks, Ricardo F.
Balancing between multiple backends from a single frontend?
Perhaps the best way to ask this question is to show what I am trying to accomplish. I got two backends with two frontends (config greatly over-simplified): backend BE_1 server server1 1.2.3.1 maxconn 2 server server2 1.2.3.2 maxconn 2 backend BE_2 server server3 1.2.3.3 maxconn 2 server server4 1.2.3.4 maxconn 2 frontend FE_1 default_backend BE_1 frontend FE_2 default_backend BE_2 So far so good, but now I need to add another frontend that balances between all 4 servers, something like: frontend FE_1 default_backend BE_1 default_backend BE_2 But this only sends stuff to BE_2, I can create a new backend BE_3 which contains all 4 servers, but this has a huge drawback that my maxconn settings are no longer respected as it is used in two places, doubling the total max. I can reduce maxconn, but then I get bottlenecks whenever load is not perfectly balanced. What is the right way to configure this? Thanks in advance! -M (In case you are wondering why this config, each server in each backend serves two separate but related requests (a common one, and a backend specific one) - I need to balance the request to specific backends AND requests for common info shared but both pools.)
