+Subject: [PATCH] This is fix for reborn of
+ https://github.com/SpiderLabs/ModSecurity/issues/334 This bug has been
+ reborn, because Apache (at least in RedHat/CentOS) since version 2.2.15-47
+ returns in same case APR_INCOMPLETE (not APR_EOF). Based on same patch I have
+ added handler for APR_INCOMPLETE.
