Example

The following example does two tasks. It first specifies a service certificate for the client to use when communicating with endpoints whose domain name is www.contoso.com over the HTTP protocol. Second, it specifies the revocation mode and store location used during authentication.

<serviceCertificate>
  <defaultCertificate findValue="www.contoso.com" 
                      storeLocation="LocalMachine"
                      storeName="TrustedPeople" 
                      x509FindType="FindByIssuerDistinguishedName" />
  <scopedCertificates>
     <add targetUri="https://www.contoso.com" 
          findValue="www.contoso.com" storeLocation="LocalMachine"
                  storeName="Root" x509FindType="FindByIssuerName" />
  </scopedCertificates>
  <authentication revocationMode="Online" 
   trustedStoreLocation="LocalMachine" />
</serviceCertificate>
