Hi THere! Here is a rehashed version of the patch cert_vucert944335 chunk fix patch used in apache_1.3.9-14.1 for potato which works for apache in woody and sid.
The only thing stopping it was a comment about EBCDIC! Got to go - test this thing on s390 as well! Uploading .debs to fix apache chunk size stuff for i386 on woody and sid NOW! Source .dsc and .diff is there if others want to build for other architectures. The i386 .deb works on my home system. Did not know how to do NMU with new security system, or someone else can look after it. Matthew? Steve?
