Error description
mod_proxy_http does not allow headers larger than 8K bytes. A directive should be added to allow the tuning of the proxy response buffer so headers larger than 8K bytes can be handled.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Users of IBM HTTP Server (powered by * * Apache) * **************************************************************** * PROBLEM DESCRIPTION: mod_proxy_http truncates large headers * * greater than 8K bytes. * **************************************************************** * RECOMMENDATION: * **************************************************************** mod_proxy_http will truncate large headers greater than 8K bytes. On z/OS, users may also see proxied requests fail due to large headers, because IHS will not translate the headers to EBCDIC causing IHS to think it is an invalid header.
Problem conclusion
mod_proxy_http was modified to allow the header size for proxied responses to be configurable via the worker parameter ResponseFieldSize. This fix is targeted for IBM HTTP Server fix packs: - 8.5.5.14 - 9.0.0.8
