Created attachment 21760 [details] This patch handles JkOptions correctly My site works on Apache 2.0.61 + mod_jk-1.2.23 + Tomcat. I upgrade my site to Apache 2.0.63 + mod_jk-1.2.26 + Tomcat, and it does not work. mod_jk logs following messages: [Tue Apr 01 19:21:55.450 2008] [20648:27] [error] jk_handler::mod_jk.c (2223): Could not init service for worker=customer An abobe trouble causes by a bug of merge_jk_config(). My httpd.conf is like a following: JkOptions +ForwardURIProxy <Virtualhost *> JkOptions +ForwardURICompat </Virtualhost> In server settings, "options" variable is JK_OPT_FWDURIPROXY (0x0004). In virtualhost settings, "options" variable is JK_OPT_FWDURICOMPAT (0x0001). merge_jk_config() merges both variables to 0x0005 and it causes an error of init_ws_service().
Thanks a lot for analysis and patch. Patch applied to 1.2.27-dev (for httpd 2.x and 1.3).
