IZ67230: ATOM WEB 2.0 CLASSIFICATION API RETURNS HTTP 404 WHEN USING IBM HTTP SERVER (IHS) / WAS CLUSTER

APAR status

• Closed as program error.

Error description

• If you invoke the ATOM Web 2.0 Classification API to access
  URLs, and the invocation includes a percent encoded URI, you
  see HTTP 404 when IBM HTTP Server (IHS) with WAS plugin is
  used.
  

Local fix

Problem summary

• IBM HTTP Server / WAS plugin partially decodes percent encoded
  URIs embedded in the HTTP request URL, specifically %2F is
  decoded to "/" and %3A to ":".
  
  The code has been updated to handle embedded "/" and ":"
  characters which have been partially decoded.
  
  Note that there are many potential causes for an HTTP 404 error.
  To confirm that this is the problem, use a TCP monitoring tool
  to capture and inspect the output from IHS. Note also, that IHS
  must have its "AllowEncodedSlashes" directive set to "On" to
  pass through any requests that include percent encoding. This is
  set in httpd.conf by adding a line containing the text
  "AllowEncodedSlashes On".
  

Problem conclusion

• This fix allows %2F and %3A characters embedded in URIs to be
  processed correctly. It is planned for delivery in 7.0.0.1
  

Temporary fix
