Some customers want to access custom HTTP request-headers. These headers can be inserted by third party products such as load balancers, application servers, or web server plugins. This parameter is assigned the value of the specified HTTP header. If the header is present in the incoming request, then SDC appends the header name to “WT.hdr.”, and the header value is assigned. For example, suppose a customer wants to log the “Accept:” header, and it comes in as “Accept: */*”. The resultant parameter would be WT.hdr.Accept=*/*. Note that values are URL encoded.
WT . hdr.<HTTP Header> = <HTTP Header Value>
