native/apache-2.0/mod_jk.c native/configure.in
xdocs/miscellaneous/changelog.xml xdocs/webserver_howto/apache.xml
Author: rjung
Date: Tue Jan 15 10:38:01 2008
New Revision: 612187
URL: http://svn.apache.org/viewvc?rev=612187&view=rev
Log:
Don't use post httpd 2.2.0 API functions when building
with new --enable-api-compatibility configure switch.
This improves binary compatibility of module builds with
httpd releases older than the release against mod_jk is build
(only between minor httpd versions).
