Adding SOAP headers to ASMX service requests
We were given a set of ASMX services to consume. We have no say in how these services are implemented. We have generated a number of proxies with wsdl.exe tool but for some reason unknown to me, these generated proxies don't have any means for including custom SOAP headers.

Basically, I need a way to add custom header data to various service calls.

I am aware of existence of SoapExtension class but unfortunately we're not allowed to use that due to supposed performance issues.

Are there any alternative ways of customizing/adding header data in SOAP requests?

Thanks
