APAR status
Closed as program error.
Error description
IBM HTTP Server may cache a partial response and then serve that partial response for subsequent requests if a client closes the connection before the full response is sent for a chunked response.
Local fix
Disabling ESI in the WebSphere plugin could make it less likely that the client hangs up while reading the response.
Problem summary
**************************************************************** * USERS AFFECTED: IBM HTTP Server users of the mod_mem_cache * * module. * **************************************************************** * PROBLEM DESCRIPTION: Partial responses were being cached * * if the client closed the connection * * before the entire response was read * * by mod_mem_cache * **************************************************************** * RECOMMENDATION: Apply this fix if using mod_mem_cache. * **************************************************************** When a chunked response is received from WebSphere through the WebSphere plugin and the client closes the browser before IBM HTTP Server has sent the full response, IBM HTTP Server is seen caching the partial response. Subsequent requests for this resource are then seen being served from cache with the partial response.
Problem conclusion
Incomplete cacheing will no longer occur in the circumstance where the connection is closed by the client during a chunked response. This fix is targeted for IBM HTTP Server fix packs: - 7.0.0.41 - 8.0.0.12 - 8.5.5.8
