Extra space in HTTP headers gives 400 error on HAProxy

由 一笑奈何 提交于 2020-01-03 02:22:15
问题 We switched from citrix to HAProxy for load balancing recently. The Problem is that for some requests HAProxy started giving a 400 Error (Which used to work well on citrix). So we moved to TCP based load balancing from a HTTP based load balancing for the time being. On further investigating we found that some requests had an extra space in the HTTP header which caused the 400 error. profileID<space>:value vs profileID:value And these requests came from the android app so we are not able to

How to load balance Kafka Boostrap with haproxy?

由 和自甴很熟 提交于 2020-01-02 08:19:23
问题 I have a kafka cluster consisting of 3 machines running on AWS: kafka1 to kafka3 I'm using the new style kafka consumers (>0.8). I know that the kafka client connects to one of the kafka servers, grabs server metadata and then connects to the brokers directly. I want to ensure that in the case of a broker failure that the clients are still able to grab metadata. For this I have an HAProxy load balancer with the following config: listen kafka bind *:9092 mode tcp balance roundrobin no option

How to route traffic (reverse Proxy) with HAProxy based on request body

由 我的梦境 提交于 2020-01-02 05:40:15
问题 I am attempting to route the following request to the appropriate servers based on the URL identified in the POST body below. I am hoping to accomplish this via a reverse proxy using HAProxy. E.g. I would like to direct all requests to HAProxy, than have HAProxy check if certain values exist in the POST body (E.g. the notification url value "pingpong"), and if this is the case, route the traffic to an endopint I will specify in the configs. POST /someURL/file.jsp HTTP/1.1 Host: 10.43.90.190

Apache Tomcat 7 Changing JSESSIONID on Every Request

由 时光怂恿深爱的人放手 提交于 2020-01-01 03:10:06
问题 This issue is driving me insane, so maybe someone could help me understand what the issue is. I have a tomcat web application being fronted by HAProxy. HAProxy is also doing SSL offloading, and is configured to use sticky sessions. I am using Tomcat's session replication feature which seems to be working just fine. The sessions appear on both appservers. For some reason, Tomcat is generating a new JSESSIONID for every single web request, and then copying the contents of the old session into
