Hi, "option accept-invalid-http-response"
was the solution. Regards, Florian On 14.01.2014 17:31, Florian Engelmann wrote:
Hi, we are using HAProxy 1.5-dev21 as loadbalancer frontend and some NGINX 1.4 servers as backend. Everything is working perfect. Great piece of software! One question: If some client sends a request like: GET something.someone This request is forwarded to the backends even if it is not a valid request. The backend (NGINX) replies with an error page 400 (Bad Request). This is an invalid response to HAProxy which will deliver a 502 (Bad Gateway) error to the client. Response to client: 2014-01-14T15:17:04+01:00 somehostname haproxy[99999]: xxx.1xx.2xx.xx:50294 [14/Jan/2014:15:17:04.648] application8089 application8089/somehostname.some.domain 0/0/0/-1/1 502 370 - - PH-- 475/441/8/0/0 0/0 \"GET usacording.com HTTP/1.0\" HAProxy error: [14/Jan/2014:16:52:07.357] backend application8089 (#11) : invalid response frontend application8089 (#11), server somehostname.some.domain (#2), event #2211 src xxx.1xx.2xx.xx:55112, session #2141081, session flags 0x0000048e HTTP msg state 26, msg flags 0x00000000, tx flags 0x08300000 HTTP chunk len 0 bytes, HTTP body len 0 bytes buffer flags 0x00008023, out 0 bytes, total 166 bytes pending 166 bytes, wrapping at 16384, error at position 0: 00000 <html>\r\n 00008 <head><title>400 Bad Request</title></head>\r\n 00053 <body bgcolor="white">\r\n 00077 <center><h1>400 Bad Request</h1></center>\r\n 00120 <hr><center>nginx</center>\r\n 00148 </body>\r\n 00157 </html>\r\n Is it possible to respond the original error (400) to the client?
