title: HTTPRIO Delphi SOAP Server error 'expects "text/xml"'
body: <p>We have an existing ISAPI DLL compiled in Delphi XE5 which validates customer login. Recently we re-compiled the dll using Delphi DX (10.1 Berlin) and found that the test client, using HTTPRIO, throws the following exception: </p>
  
  <blockquote>
    <p>Ex: ESOAPHTTPException: Received content of invalid Content-Type
    setting: text/html - SOAP expects "text/xml".</p>
  </blockquote>
  
  <p>We were not able to fix the problem and had to revert back to using Delphi XE5 to amend and re-compile the DLL.</p>
  
  <p>I was wondering if anybody else had a similar problem with SOAP servers.</p>
