Error description
Use of mod-deflate with SSL can cause network fragmentation.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: IBM HTTP Server users who use SSL and have * * also enabled the optional mod_deflate * * module * **************************************************************** * PROBLEM DESCRIPTION: Responses are fragmented into many * * smaller packets when the mod_deflate * * and mod_ibm_ssl modules are both used. * **************************************************************** * RECOMMENDATION: Apply this fix if using both SSL and the * * mod_deflate module. * **************************************************************** The fix is disabled by default. The new environment variable 'IHS_SSL_SEND_MERGE' must be defined in order to enable the fix. For example, on a Unix Operating system you could edit bin/envvars and add these lines: IHS_SSL_SEND_MERGE=x export IHS_SSL_SEND_MERGE (where "x" can be anything - its actual value doesn't matter.)
Problem conclusion
A fix is being provided to resolve network fragmentation when using mod_deflate with SSL. This fix is targeted for IBM HTTP Server fixpacks: - 6.1.0.39 - 7.0.0.19 Future releases of IBM HTTP Server will act as if the property IHS_SSL_SEND_MERGE is always set, and the behavior cannot be disabled.
