Do you mean POST to /check where post body is the SOAP envelope ?

I think you can (ab)use http version to send body with option
httpchk

(https://cbonte.github.io/haproxy-dconv/1.8/configuration.html#option%20httpchk)

One example for sending xml post:

Hi,

You can also forge a http post with the tcp-check. This would be less hacky.

Do you mean POST to /check where post body is the SOAP envelope ?

> Any suggestions and help would be appreciated!

I think you can (ab)use http version to send body with option httpchk
(https://cbonte.github.io/haproxy-dconv/1.8/configuration.html#option%20httpchk)

One example for sending xml post:

Re: SOAP service healthcheck

Hello,


One option is to implement a sidecar/watchdog service which queries the 
SOAP service directly and exposes a /check URI that HAProxy can use for 
the http-check.



I'm not sure if there's a direct way to POST data to the http check, I 
will let you know if I find one.



Hope this helps.


Best regards,


Bruno Henc

I need to check if a SOAP service responds before sending requests to 
the server. I've read about this option:

       option httpchk GET /check
        http-check expect string OK
I think, it's what I need. But is there a way to pass SOAP envelope to 
this "/check" service?


Any suggestions and help would be appreciated!

SOAP service healthcheck

[Māra Grīnberga]

Hi,

I'm new to Haproxy and I've a task for which I can't seem to find a
solution online. Probably, I'm not looking in the right places.
I need to check if a SOAP service responds before sending requests to the
server. I've read about this option:
   option httpchk GET /check
http-check expect string OK
I think, it's what I need. But is there a way to pass SOAP envelope to this
"/check" service?

Any suggestions and help would be appreciated!

Best regards,
