Error description
NCSA access logs %b option output displays as "-" instead of the size of the response in bytes.

Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server Version * * 8.5.5, * * 9.0, and Liberty Full Profile users of the * * National Center for Supercomputing * * Applications * * (NCSA) Access Log * **************************************************************** * PROBLEM DESCRIPTION: The NCSA access data log's %b and %B * * may * * return the incorrect response body * * size. * **************************************************************** * RECOMMENDATION: * **************************************************************** The %b and %B directives utilize the content-length header, if present, to log the response body size. When this header is not present, the directives use the HTTP Channel to determine how many bytes were written out for the response's body. However, this approach could erroneously report response sizes in cases where there was no body sent on the response. An example of this can be seen in HEAD requests, which could have a content-length header set and, by specification, will not return a body on the response. While the expected result should read "-" on %b and "0" on %B, they would both log the content-length header value. Additionally, both directives have a problem regarding chunked encoded responses. In these cases, both directives will currently log "-".
Problem conclusion
The HTTP Channel was modified to correctly track the amount of bytes written by all responses. The NCSA log's %b and %B directives were modified to use this HTTP Channel change to correctly report response sizes. The fix for this APAR is currently targeted for inclusion in fix packs 8.5.5.13, 9.0.0.6, 17.0.0.3.
