Problem summary

• ****************************************************************
  * USERS AFFECTED: Any IBM HTTP Server that receives requests   *
  * with a URI that maps to a local filename whose length exceeds*
  * the local system PATH_MAX setting. This issue exists on IBM  *
  * HTTP Server versions prior to 6.0.2.35 and 6.1.0.25. IBM HTTP*
  * Server version 7 is not impacted.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: When a request URI results in a local   *
  * path that exceeds the server's operating system PATH_MAX     *
  * limit, a 403 (forbidden) is returned but nothing is logged in*
  * the server's error log to explain why.
  ****************************************************************
  * RECOMMENDATION: Apply this fix if you get 403 responses and  *
  * you have very long urls or very long filepaths.              *
