<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">     <s:header>         <action s:mustunderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">https://(skiped)</action>     </s:header>     <s:body>     ...     </s:body> </s:envelope> 

how can log full raw request in client? must this

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:header> <o:security s:mustunderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <u:timestamp u:id="_0"> <u:created>...</u:created> <u:expires>..</u:expires> </u:timestamp> <o:binarysecuritytoken> <!-- removed--> </o:binarysecuritytoken> <signature xmlns="http://www.w3.org/2000/09/xmldsig#"> <signedinfo> ... </signedinfo> <signaturevalue>...</signaturevalue> <keyinfo> <o:securitytokenreference> ... </o:securitytokenreference> </keyinfo> </signature> </o:security> <action s:mustunderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">skiped</action> </s:header> <s:body> ... </s:body> </s:envelope> 

upd. security options binding

 <security mode="transportwithmessagecredential">     <transport clientcredentialtype="none" proxycredentialtype="none"       realm="" />    <message clientcredentialtype="certificate" algorithmsuite="basic256" />  </security> 

this may help:

public object beforesendrequest(ref message request, iclientchannel channel) {     messagebuffer buffer = request.createbufferedcopy(int32.maxvalue);     request = buffer.createmessage();     log("request:" + environment.newline + buffer.createmessage());     return null; }
