Hi Greg,
a possible solution is to add headers to your service config like:
<services>
<service name="WcfService1.Service1">
<endpoint address="http://localhost:9000"; binding="basicHttpBinding"
bindingConfiguration="" contract="WcfService1.IService1">
<headers>
<myTag>My Custom Value</myTag>
</headers>
</endpoint>
</service>
</services>
This will add the the value defined in the tag to the soap value in every
call and allow you to extract it in your service implementation through the
OperationContext. I don't think adding a behaviour is necessary as this
might imply that you want to inspect and somehow modify messages at runtime.
If you are only ever going to pass the same value, and provided the client
and service agree on the headers, this is all you would need to do.
Hope this helps.
