APAR status

• Closed as program error.

Error description

• Similar to APAR IC93918: "DATAPOWER MIGHT NOT PREVENT SENDING
  MULTIPLE HTTP CONTENT-LENGTH HEADERS WHEN MAKING A URL-OPEN
  CALL" except this is for Content-Length headers with unusual
  case syntax.
  

Local fix

• Update a stylesheet to check for and omit duplicate
  Content-length headers.
  

Problem summary

• Affected are DataPower configurations that use the XSL
  stylesheet extension element dp:url-open with the http-headers
  parameter.
  
  If the http-headers parameter supplied contains the
  "Content-Length" header with unusual casing (e.g. Content-length
  with a lower-case L), the header is incorrectly added to the
  HTTP request, resulting in an invalid HTTP request.
  

Problem conclusion

• Fix is available in 5.0.0.13, 6.0.0.5 and 6.0.1.1.
