The variable name is only for developer reference, the value of the variable is what is actually returned to the client. The example that follows shows how a new header can be added to a reply.

<!--- Add a new header value --->
<SASET NAME=HEADER.variableName VALUE=value>

<!--- A working example --->
<SASET NAME=HEADER.ContentType VALUE="Content-Type: text/wml">
         

The XML samples that are available show how the Content-Type is changed from the default text/html to text/xml; .xmlByCol and .xmlByRow
