WCF Soap Actions in HTTP header or SOAP header?

Question

I\'m a little confused about how SOAPAction is implemented in WCF (and other web service frameworks for that matter).

In a test client, I have a Client Message Inspe

Seems to me as if those two are equivalent, no? I guess Fiddler just interprets that SOAP header "", calling it "SOAPAction". The value appears to be the same, no?

What you get from the Client Message Inspector is the raw XML data (the raw format of the SOAP message) as it travels across the copper wire (or fibre). What Fiddler gives you is a higher-level HTTP-oriented interpretation of that same XML message, I would say.

Judging from other blog posts and articles I've found on Fiddler and SOAP (e.g. this blog post - check out the "Sample Capture" section towards the end), it almost seems to me as if Fiddler will strip out the SOAP headers and interpret / show them in a custom format, leaving just the SOAP body to be shown as body of the message being displayed.

Is there an actual technical problem? Or just a question of how to interpret the two formats?
