Re: http-check string and rerturn code != 200 behaviour
Hi, Thank you for your answer. I changed my configuration like this : tcp-check send GET\ /mycheck\ HTTP/1.1\r\nHost:\ myhost\r\nConnection:\ close\r\n tcp-check send \r\n tcp-check expect string HTTP/1.1\ 200\ OK tcp-check expect ! string healthStatus:Unhealthy And it works very well. Even in SSL. You now have my eternal gratitude :) Sébastien Rohaut 2015-02-16 22:22 GMT+01:00 Baptiste bed...@gmail.com: On Mon, Feb 16, 2015 at 9:29 PM, Sébastien ROHAUT sebastien.rohaut@gmail.com wrote: Hi, I'm using an http-check expect string to test the presence of a certain string in the body response.

Thank you, Sébastien Rohaut Hi Sébastien, You can write such séquence using tcp-check, sending your HTTP request with tcp-check send and matching with two consecutive tcp-check expect rules: tcp-check expect string HTTP/1.1\ 200\ OK tcp-check expect ! string healthStatus:Unhealthy Baptiste

Re: http-check string and rerturn code != 200 behaviour
Of course ! A very good idea ! But the better should be to accept multiple http-heck expect :) 2015-02-17 10:25 GMT+01:00 Baptiste bed...@gmail.com: On Tue, Feb 17, 2015 at 10:12 AM, Sébastien ROHAUT sebastien.rohaut@gmail.com wrote: Hi, Thank you for your answer.

That said should not be there for 1.6... Baptiste
http-check string and rerturn code != 200 behaviour
