Subject: Fix display of response headers in AccessLogValve:
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=b3dbbf9f78dcd2e218dc215c30cbf5402c400f88;p=tomcat7.0

Fix display of response headers in AccessLogValve:
1. When no headers are there, display "-" instead of empty string
2. Do not forget "," between multiple values
TC6 already does that but it was broken here in r767956

git-svn-id: https://svn.apache.org/repos/asf/tomcat/trunk@1088458 13f79535-47bb-0310-9956-ffa450edef68
