What is the correct way to proxing to any remote webservice? How to use  
nginx in front of IIS or other web server, who serves webservices?

As an example we have any remote SOAP webservice at  
[http://B:8089/getClientService/getClientService?wsdl](http://B:8089/getClientService/getClientService?wsdl). In SOAP document  
of  
these webservice we have endpoint location:  
…  
  
  
\<soap:address  
location=“[http://B:8089/getClientService/getClientService](http://B:8089/getClientService/getClientService)”/\>  
  
  
…

If we use proxy\_pass:

server {  
listen 80;  
server\_name A;  
location /{  
proxy\_pass [http://B:8089/](http://B:8089/);  
}

nginx won’t rewrite(or change) SOAP’s endpoint address to itself, so any  
futher SOAP requests will fail, because requesting side makes request to  
direct host described at SOAP endpoint location ☹

Thanks

You want to change “soap:address” URL on-the-fly to point next SOAP  
request(s) to [http://A:80/getClientService/getClientService](http://A:80/getClientService/getClientService), right?

Did you try sub\_module?
